AIR DISCHARGE SYSTEM
Dry bulk trailers are discharged using air pressure and are referred to as pneumatics. The discharge, aeration, top air, and blow down piping are described in a dedicated section of this manual. This refers or the intended use of the trailer, valves, seats and seals of a trailer that is intended to be used in the transportation of food products.
Load carrying cavity of trailer.
Measured by a pressure gauge located in the hopper area street side. Line pressure is generated by the air supply from a blower introduced into the discharge system. This pressure should be lower than the tank pressure. essure relief device that protects the trailer from being over pressured. The pressure relief device must always be in proper working order. Often referred to as full trailer. It is a trailer with wheels at the front and rear. The front axle can rotate because there is a roller bearing (turntable) between the axles and the tank as Landing legs that are not adjustable or carried on the trailer. They are used to support an empty trailer. Measured by a pressure gauge located in the hopper area street side. Tank pressure is generated by the air supply from a blower introduced into the hopper. This pressure should exceed the line pressure for product to discharge.

FABRIC AERATION BOTTOM
TRAILER DISCHARGE AIR SYSTEM AERATION: Aeration can come in several forms but they all are designed to introduce air into the load
of the hopper above the outlet. These cones can also be mounted in a plate or plenum arrangement adjacent the outlet. Another aeration design is fabric installed in the bottom of the hopper that allows air to pass through it to aerate the product. This design can also
used to supply air to the individual hopper. In some applications there may be only one aeration valve that supplies air to manifold feeding all the hoppers. AIR SUPPLY: The air supply line originates at the front of the trailer and transports “hot air” from the blower to the trailer. It is then diverted on demand to the aeration line and the discharge line. The air supply is coupled by a hose to the tractor, lead trailer, or stationary blower and transports all the air required to operate the trailer(s). This air supply line will have a one-way check valve at the front of the trailer to protect against air reversing back towards the blower. Pull trailers will have an air supply line under the drawbar that supplies air to the pull trailer.
Do not allow the tank or line pressure to exceed the air supply line pressure causing the product to potentially reverse toward the blower.
BLOW DOWN: The blow down line is plumbed into the air space at the top of the trailer and run down to the ground level where excess tank pressure can be exhausted. At the bottom of the unloading. This line can exhaust product dust and operators and personnel should stand clear of the exhaust outlet. The blow down piping assembly will also typically include a pressure relief device set to protect the tank from being over pressured.
Do not transport product under pressure.
TOP AIR: The top air line is an added feature to the standard blow down line. Using the same plumbing to the top of the tank as the blow down, it is used to add air pressure to the tank on top of the product. Some products need top air pressure to optimally discharge. The top air supply is
valve. Not all trailers have a top air line.
CHECK VALVES: Check valves are installed upstream of the discharge to protect against air reversing in the lines. installation technique and orientation is important for a check valve to work properly. These valves can contain springs and gaskets that require maintenance. Keep these valves in proper working order so they can properly protect the air system.
the handles are extended for easier access. The disc, stems, seats, and seals of these discharge valves are in contact with the product should be properly matched for the product to prevent contamination. GRAVITY DISCHARGE: Sometimes products are discharged by gravity and provision may be provided such as a drop tee at the bottom of the hoper allowing product to empty straight out the bottom of the trailer. Other designs might use a gravity discharge valve with a dust cover to do this same operation. DISCHARGE: Discharge lines may run the length of the trailer connected to all the hoppers or it might be a single discharge in the case of single hopper trailers. The discharge outlet is typically a cam and grove outlet that the operator attaches the discharge hose to and also connects to a silo or some other form of product storage Y-BRANCH DISCHARGE: This design can typically be found on a single hopper trailer. It allows air to be introduced to the product down stream of the discharge valve. This design includes a check valve at the y-branch. SILENCER: Silencers are optional devices installed in the air system to help quiet the noise of the air movement upstream of the product introduction points. These can be mounted on the truck or trailer and can be inlet or outlet silencers. Typically silencers are mounted on the trailer down stream of the blower. PRESSURE RELIEF DEVICE: A pressure relief device is part of the air system and protects the tank from being over pressurized.

DRAWBAR & TURNTABLE
ADJUSTABLE DRAWBAR HOUSING:
Some drawbars have an optional adjustable drawbar housing. This allows the drawbar reach to be extended and retracted. The adjustable drawbar clamp housing must be kept tight when the trailer is in operation. All safety cables, air, and electrical lines must also be properly connected no matter the drawbar reach location.
Before sliding the adjustable drawbar, set the
stop bolt is secure at the end of the slider tube. All air & electrical lines and safety cables must be disconnected and clear. Stand clear of the drawbar when adjusting the drawbar reach. After sliding the adjustable drawbar, reconnect the air & electrical lines and secure the safety cable.
Periodically check and always maintain a tight drawbar slide mechanism.
43 DRAWBAR & TURNTABLE
EXTENDING OR RETRACTING THE DRAWBAR:
The adjustable drawbar housing has three grip nuts and two separation bolts. Back off the three grip nuts to release pressure on the slider tube, then further open the housing using the two separation bolts. These actions will allow the housing to open up so the reach tube can slide in the housing. Stand clear of this area during this operation and extend or retract the drawbar in a safe and secure manner. Once the drawbar is appropriately sized, tighten the the housing to come together. Next tighten the three grip nuts going from one to another, two or three time until the housing is evenly tightened. Finally, cinch the two separation bolt down so they do not back out. Reinstall the air/ electrical connections and secure the safety cable.
Do not lubricate the reach tube or slider housing.
LADDERS, WALKWAYS, STEPS AND DRAWBARS Beall equipment can have a variety of ladders, steps, walkway, and drawbar designs and their locations are not limited to those discussed below. These items are meant for your safety and their surface texture, width, height, angle, and overall design can vary. Care needs to be taken when using all of these surfaces. LADDERS can be at the front, side or back of a Beall product depending on the design demands. Access can be from the ground via steps, drawbar, or from truck or tractor frame. Some ladders can have dual rails and can be used to access drawbars, platforms or other walkways and surfaces. Ladders can also be mounted at a slope or angle.
LARGE AND SMALL CUBE LADDER INSTALLATIONS
STEPS can be installed at front, side, back or on a slope of a Beall product depending on the design demands. Steps can also access drawbars, platforms, ladders, or other walkways and surfaces.
WALKWAYS can be located on the top, side, front, or rear of a Beall product depending on the design demands. Some walkways may contain hazards and extreme care must be taken when navigating any surface with known or unpredictable hazards.
DRAWBARS with a walkway surface are typically found on a pull trailer design. Do not attempt to walk on a drawbar without a surface intended to be used as a walkway. Treat drawbar walkways with the same care as any other walkway.
Watch your step when using access devices.
Use both hands when climbing on or off equipment.
Surface could be slippery.
WATCH YOUR STEP TANK ACCESS EQUIPMENT MUST BE PROPERLY MAINTAINED BY TANK OWNER.
No part of this equipment including the top walkway is intended as a heavy work area. Areas other than ladders, steps, and walkways are not intended as access.
Ladders, steps, and walkways are intended to provide access only when other external facilities are not provided.

Make sure all gaskets and seals are in good condition. Check all the plumbing for bolt tightness to avoid spillage.
closed and secure prior to loading and while in transit.
Replace any missing or otherwise impaired dome gasket before loading.
48 PRE-LOADING INSTRUCTIONS
Before opening the blowdown line, make sure everyone is clear of the exhaust stream. Open blowdown valve before loading. Excess product in the blowdown line can plug the pressure relief valve. Be aware of any product spill out of blowdown line. Some load facilities require this valve to be closed when loading.

TOP AIR/ BLOW DOWN HOSE
TOP AIR VALVE
Make sure that the correct placards are in place, if required, before loading.
If the trailer is loaded by volume make sure the trailer is empty before loading.
Set the trailer parking brakes in the cab before loading.
Be aware of the maximum loading temperature rating and do not load a product above that temperature. Loading of a product at a higher temperature can cause structural damage to the tank. Be aware of the maximum product density and the maximum product load. Do not exceed the Gross Vehicle Weight Rating. If loaded past this point, structural damage may result. If your trailer is equipped with an air suspension system, load the trailer with the tractor attached in order to maintain air pressure in the suspension system. If you must disconnect the tractor, support the trailer at the kingpin plate and exhaust the air from the suspension. Do not load a trailer that is being supported by non-load bearing landing legs. When top loading, make sure that the loading pipe is properly secured to prevent spillage. Make sure that the manholes and blowdown valves are properly sealed before moving the trailer. Overtightening the covers can cause damage to the gaskets.
Loading facility requirements can vary. Follow all loading facility instructions for safe loading.
Materials and dust are potentially harmful. Avoid contact with them by keeping clear of open manholes and vent outlets. DO NOT attempt to load this equipment by vacuum unless it is vacuum-capable by design, as indicated on the serial plate.
Check to make sure that the pressure relief device is in proper working condition. Make sure that the valve body and exhaust vents are kept clear of buildup and other obstructions. Periodically check to ensure thread tightness. Blower vibration may loosen them over time. Ensure that all the gauges are in proper working order. If the gauges are unresponsive during working conditions, check for clogs. (1) Tank air pressure gauge (1) Line air pressure gauge
Start the blower and pressurize the tank through the aerator(s) to normal
the product as well. The line pressure should read 0 during this process. Make sure the blow down valve is closed. (see TTMA RP No. 83,84)
All product valves must be closed before removing the discharge cap. Beware of possible product retention under the cap when it is being removed. Make sure that you have a good connection of the discharge hose before opening the product valves.
Open the discharge line control valve part way. Gradually open one of the product valves. Adjust the line control valves to maintain a steady tank pressure. As tank pressure decreases, close the line control valve a little bit to increase the tank pressure. If the tank pressure is increasing, open the line control valve wider to reduce the tank pressure.
The top of the hopper is not intended as a heavy work area. The ladder and walk surface are intended to provide access only when other facilities are not provided. Personnel should never be on top of the hopper while it is pressurized. The working line pressure of the unit is 14.5 psi. If there is a discrepancy between the gauges, check the system for clogs.
As the product level reaches within a few feet of the product valve on the hopper being unloaded, the pressure will begin to fall off. Close this product valve and open and adjust another one. Cycle through the hoppers in this manner in order to have the smoothest possible unloading.
All of the check valves must be operational to prevent product backup into the supply lines. Do not exceed the working pressure of the system. Check and maintain the vacuum and pressure relief devices regularly. Do not close the domes after cleaning until the hopper has cooled. (see TTMA RP No. 84) Opening the product discharge valve too fast may cause line plugging. When unloading, make sure all couplings and connections are secure to prevent spillage and material loss. Make sure the relief valve is operational and is set to operate at 5 psi over the operational pressure of the tank. The valve
As the hoppers start to empty out, it may become necessary to close the line control valve down further to divert more air to the tank.
If the unloading bin is improperly vented, a pressure reading will show up on the gauges after the product has been discharged. Determine the cause of this problem and correct it before proceeding. The tank may be under pressure. Do not open the dome. Do not open the valves. Do not remove any couplers or hoses until the pressure has been relieved.
The aerators will begin to vibrate the shell as the hoppers empty out. This will help to remove any material still clinging to the shell of the tank. The line control valve will have to be closed even further during this process.
When both tank and line pressure begin to fall simultaneously, the line
may still be in the discharge line.
After the dischar valve and shut off the air source.
The manholes may be opened after all pressure gauges read zero and there is no more air coming out of the blow down valve.
The manhole cover assemblies must be kept clean in order to permit proper sealing of the gaskets. Clean the manholes every time before closing.
Manhole cover assemblies must be properly adjusted to retain pressure. Make sure all safety and lid retention devices are in proper working order.
UNCLOGGING PLUGGED LINES Signs that the discharge line is plugged: 1. The unloading hose does not move. 2. Tank and line pressure increase simultaneously. 3. The pressure relief valve opens. STEPS FOR CORRECTING A PLUGGED LINE.
1. Close all product valves. 2. Close the aeration valves. 3. Open the line control valve completely. Repeat a few times to see if changes 4. If the line remains plugged, stop the air source, open the blow down line and completely depressurize the tank. Then close the blow down line. Put full air pressure on the product line and quickly open the product valve on the least full hopper. This should be done after the pressure relief valve activates. This may take many times to clear the line. FOOD GRADE TRAILERS Food Grade trailers should be properly cleaned on a regular basis after unloading. The cleaning detail will depend on the product and the tank interior complexity among other reasons. Piping connections can be provided with easily removed clamps to reduce cleaning time. Gaskets, seals, valves, and material should be food grade quality and maintained to protect the product. Hopper outlets can be provided with drop tees for more accessible cleaning. Gravity doors and dust covers can be opened or removed for proper cleaning.
removed or disconnected for cleaning purposes.
INTERIOR CLEANING Interior cleaning is the carriers’ responsibility and should satisfy not only your established in-house procedures, but also those industry, religious, governmental, and customer requirements to name a few. Know the cleaning requirements for your operation. Proper cleaning is not limited just to equipment transporting food grade products and should be an integral part of carriers’ quality program.
