In some cases, traditional mechanical refrigeration technology can be used to keep internal temperature.In these cases, the heat that extracts can be used to preheat the hydration liquid that uses in first assembly in heat exchanger 50.In other cases, the inactive gas such as carbon dioxide, nitrogen or fluorocarbon of liquefaction can be used as cooling agent.As be shown as 51 one group nozzle sets that suitably is provided with and inject this gas with 0psig, thereby reduce temperature significantly.Along with this gas is heated and rises, it can be sent into a pressure recovery ventilation blower 52 by a supply fan on the compressor, to obtain recompression and recirculation.Similarly, the heat that extracts from the gas of recirculation can be used to heat hydration liquid.Under any circumstance, be preferably at inlet 39 and outlet 44 places and comprise a system for partition wall or air curtain system, these regional gases are invaded and outflow to reduce as much as possible.Because dry ice can be stayed on the medium that freezes and other outer solid can accumulate on the medium that freezes, outlet 44 is guided to one second vibrating screen conveyer 45 to the hydration medium that freezes, thereby removes these particles.Can adopt suitable setting easily and this material is recycled to inlet 39 ＇.
If assembly is as illustrated in fig. 4 by stacked, one as the occupied space of described system herein can be as small as an area of three feet wide eight feet long.Its height will be lower than eight feet.Machine with this size can per hour be handled the hydration liquid of 1200 pounds of as many as, and this will be enough to the band that is laid with polymer of 300 feet long 15 inches wide of complete hydration two volumes.The medium of this quantity will enough per hour respectively have at eight arranges one deck in two cubic feet of volume casees; Therefore, it is very desirable for concerning going bad or thermo-responsive product refrigerates the small-sized shipment operation of shipment packing.
Referring to Fig. 5 to 7, second embodiment has been described wherein.Fig. 5 has shown the hydration freezing equipment 110 with critical piece of the present invention.The critical component of equipment 110 is accommodated in the traditional heat insulation refrigerated trailer 111.This trailer comprises the air-conditioning unit 112 that is positioned at a standard under the trailer, and this air-conditioning unit 112 provides cold dry air to device interior.Trailer shell 113 comprises the insulating portion that makes the interior parts of trailer avoid being exposed to the outer high ambient temperature of trailer.A mobile generator 114 provides electric power to all systems of equipment, and comprises the jockey that is used for the external power connection, thereby makes the on-site external ac power source of consumer can be utilized for power devices.An outside water jockey 131 makes it possible to utilize consumer's the water on ground.
Equipment 110 comprises three main separation A, B and C, and they are separated by preceding dividing plate 115 and rear bulkhead 120.Each dividing plate includes a passage doorway (not shown), thereby makes the workman can pass by entire equipment to provide service to all separations.Preceding separation A is used as the memory block 125 of media roll 117.The ThermaFreeze medium that is applicable to this equipment is that the form with 15 inches or 30 inches wide 300 feet long volumes provides.This volume is made of the continuous band such as the medium of 2 ounces of polyacrylic adhesive-bonded fabrics.This band comprises a plurality of " cells ", and these " cells " have about 2 inches * 2 inches size usually and having between each cell between 1/4 inch seal area (margin).On this adhesive-bonded fabric, be stacked with a plastics polypropylene screen, to form 2 * 2 cells.Under situation about having between each cell between 1/4 inch seal area, 15 inches index zone transversely has 6 cells, thereby in one 300 feet volume 9000 cells is arranged, and the cell number in 30 inches wide volumes then is its twice.Each cell comprises the super absorbent polymer such as the sodium salt of the crosslinked polyacrylate that meets the FDA standard (sodium polyacrylate).Film is stacked on the adhesive-bonded fabric and polymer is arranged on process in each cell, by United States Patent (USP) the 5th such as people such as Murray, 628, equipment in No. 845 (this patent is used as list of references at this), and realized automation, thereby make the use of this medium more economical.Though it is good that these materials are used for effect of the present invention, the other materials with similar physical property can be used for the present invention too and obtains good effect.As time goes on the applicant expection will develop various types of media adapting to the needs of shipment, and the present invention described here designs for the various types of media sizes that adapt to continuous evolution.
In the preparation of equipment operation, a volume medium 117 is loaded onto in the rotating shaft 118 of a motor driving, it is deployed on the transfer roller 119 on the entire equipment.A motor in the rotating shaft can convenient medium expansion to the transfer roller 119, and in fact this motor can be combined into one with transfer system on electric, thereby makes the motion of volume 119 cause the cooperative motion of rotating shaft motor; Yet what it is contemplated that is, is with and send and driven roller 121 when being started when band is transmitted system, and transfer roller 119 self will provide enough power to launch media roll.Most of transfer roller 119 all is driven, rotates in response to driven rolls 121 is pulled through the band of equipment.As seen from the figure, can be along with the difference of consumer's application and difference according to length-this length of the transfer system of being installed, driven roller is set at the different key position in the equipment.In some applications, if transfer system is sufficiently short, single driven roller just is enough to band is pulled through equipment.In addition, though shown several rollers in these figure, what it is contemplated that is that the density of roller will change along with the different of media type with the position.
Referring to Fig. 7, as seen each transfer roller 119 and driven roller 121 are surrounded by rubber high smooth property, that have pattern or Teflon usually TMAlloy 122 is to support and to carry this band and make it pass through equipment.Each roller is supported in rotating mode by conventional apparatus well known in the art in each separation, and, the mechanical aspects of pair roller and transfer system is not done further to discuss because the method for rotating is not crucial for the operation of this equipment and do not embody novel aspect of the present invention.Each roller comprises a series of protuberance 123 of the outside that is positioned at roller, and band have along between the second and the 4th seal area of band, the perforation 124 that is in correspondence position, be used to accept the corresponding protuberance on the roller, as shown in the figure.This traction is presented clamping and the enabling capabilities that has strengthened roller when band is pulled through equipment is set.
Referring now to Fig. 6,, in separation B a hydration tank 126 and a freezing chamber 127.Hydration tank 126 comprises a pump/heater assembly 128 and unsteady detector 129, is used for controlling the liquid level of water temperature and jar 126.Outside water coupling part 131 makes it possible to be connected with the water source at consumer scene, with through pump 128 to jar 126 water fillings, and discharge port 132 makes it possible to promptly jar be discharged after the medium preparation is finished.Temperature Detector in the pump 128 and a heating element heater remain on 90 °-150 °F (being tepor) to the water temperature in the jar.A driven roller 121a adjacent with dividing plate 115 is being pulled through seam on the dividing plate 115 and through opening 134 it being drawn in the aqueous environment of the jar 126 of encirclement with 117.Roller 119 in jars 126 is with 117 as shown in figure under the pulling water surface, and will be with 117 water that sent tepor with controlled speed, so that the polymer in the cell reaches optimization to the absorption of water.Though show it is the jar of complete immersion type, the hydration process of replacement also is suitable for the hydration of medium.For example, a kind of water that provides constant (operating) water nozzle water supply, that be arranged on the top dispose-wherein to be provided is injected into by being with that jar is advanced, and will provide suitable hydration result.With a kind of nozzle that is located at the top replacement water storage tank is set, only needs to change the distribution duct of heating/pump installation 128 so that the submerged position of water from jar is recycled to nozzle.
After hydration, be with 117 to be raised on the water surface 136 and driven rolls 121b is pulled through a heat insulation doorway 138 and enters freezing chamber 127.Doorway 138 is made of a series of inviscid longitudinally rubber catch of the support that is subjected to a cover with appropriate size, so that be with 117 can pass through heat-insulating wall 139, and wallboard 139 is also as shown in figure round freezing chamber 127.Transfer roller 119 is positioned at chamber 127, increasing vertically advancing of band, thereby increases with the open-assembly time under 117 the freezing conditions in freezing chamber.Chamber 127 comprises special-purpose refrigeration system.The expanding nozzle 141 of paired CO2 tube 142 in chamber 127 provides gas.Mechanical refrigeration unit 143 cools off by the CO2 system.Machine assembly 143 is traditional, but can have higher cooling capacity, to realize lower temperature in chamber 127.Shown traditional interchange parts, condenser 144, evaporimeter 145, compressor 146, expansion valve 147, refrigeration lines 148, air duct 149 and blower fan 150 all is positioned at the top in chamber 127; Yet various types of systems-all those systems as known in the art-can be set at other position are with performance and the economic benefit that realizes optimizing.Temperature Detector and control circuit (not shown) are being controlled the interaction and the operation of two cooling units, thereby keep below-10 temperature in the chamber.This temperature is not crucial for refrigerating process, as long as kept being lower than 20 temperature in chamber (127).Yet, test shows, the temperature that is being lower than-10 can realize the freezing rapidly of cell in the mode of optimizing.In addition, though shown two types cooling system, the applicant thinks that one or another kind of individual system is suitable for keeping cryogenic temperature in the chamber.
After freezing, the driven roller 121c adjacent with dividing plate 120 with 117 be pulled through chamber 127 and with this band sent have with doorway 138 similarly structure back doorways 151, by an opening on the dividing plate 120 and enter the cutting area 150 of separation C.Though whole medium has absorbed some moisture content, water concentrates in the cell of medium, and remains the comparison flexibility with 117.This makes is with 117 can continue on transfer roller and can not hinder it to pass through equipment significantly.
