A pneumatic door system and a method of using the same are disclosed herein. According to one embodiment, a trailer may include a seamless main door and at least one side door. The doors may be configured to be locked shut with a system of pneumatic locks. The main door may be configured to open and close as controlled by pneumatic pressure applied to a door cylinder. The pneumatic system may be configured to be controlled by an interior control box. The pneumatic system may be configured to operate off of pneumatic pressure in an auxiliary air tank, the pressure being protected by a series of one-way check valves. The pneumatic system may also be configured to operate wirelessly using RFID or Bluetooth technology, among other things, to secure the cargo and facilitate ingress and egress to the trailer.
摘要:
A method for adjusting pressure at an inlet of a blast freezer. The method includes positioning an airfoil proximate to the inlet, the inlet having a perimeter. The airfoil includes a strip of material having a length and being attached to the freezer along at least one side of the inlet, the strip of material being spaced from the perimeter of the inlet by an offset distance. The offset distance at any location along the length of the strip of material is the closest distance between the strip of material and the perimeter at that location. The offset distance varies substantially along at least a portion of the strip of material. Cold air is flowed in the blast freezer past the inlet and over the airfoil so that the flow of air past the inlet is disrupted and creates a resultant adjustment to the air pressure at the inlet.

A cold pack comprises a main body; an inner chamber defined by the main body; and a phase changeable medium disposed in the inner chamber. The phase changeable medium includes a polymer and a peptide, which can be a component of a peptide-containing composition. In specific examples, the polymer is an organic polymer, such as an organic superabsorbent polymer, and the peptide is a lateral root hair promoting peptide.

A refrigerant bunker comprises a refrigerant covering comprising a first thermally insulating material configured to enclose a solid refrigerant and an outer container comprising a container body and a container cover. The container body comprising an outer surface, an inner surface defining a partially enclosed space configured to accept the solid refrigerant and an opening for accessing the partially enclosed space. The container cover is configured for covering the container opening. The container body comprises a second thermally insulating material. A plurality of spacers protrude from the inner surface of the outer container in the partially enclosed space. The plurality of spacers are positioned to have gas fillable gaps between the spacers. Coolers employing the refrigerant bunker are also disclosed.

摘要:
An article of manufacture for use as an insulated overhead door that is designed to roll open and closed in tracks, with a sheet of thermoplasitc material that acts as the outer door membrane and barrier to entry, a sheet of insulating material that acts as a base insulating barrier adhered to the thermoplastic membrane.
摘要:
A refrigerated bunker comprising a body defining an enclosed space for holding dry ice; at least one ventilation port defined through an outside wall of the body, the ventilation port configured for venting gaseous carbon dioxide from the enclosed space as the dry ice sublimates; and a port controller configured for selectively interrupting the ventilation port.
摘要:
A system for allowing a loading dock door to release from guide tracks. The dock door includes wheel-and-axle assemblies which are mounted to the door and which include wheels biased towards a position in the tracks. At least one of the tracks has a cross sectional profile which enables the wheels disposed in the one of the tracks to move out of the one of the tracks when the door is struck with sufficient force.
