Abstract
The utility model relates to a tray used on a shelf of a vacuum refrigerating drier, and belongs to the field of vacuum refrigerating drying of foods, medicines, biologicals and the like, as well as drier machinery manufacture. The tray has a simple structure, a lower cost and a wide range of application, and is mainly composed of inner frames, outer frames and a bottom, wherein the bottom is tightly pressed between the inner frames and the outer frames; the inner and the outer frames adopt stainless steel plates or aseptic engineering plastics; and the bottom adopts stainless steel screen, stainless steel thin plate, aseptic plastic film or strong fiber, and has a small thickness of 0.15mm to 1.0mm. The tray adopting materials with excellent flexibility can be contacted with the surface of the shelf in the largest contract area, and is replaceable, so that the temperature transfer performance is far better than that of a stainless steel tray, and is applicable to the processing such as drying or refrigeration drying to foods, Chinese and Western medicines, chemical industry, subsidiary agricultural products and the like to achieve various process purposes.
Description
Technical field
The utility model relates to the pallet that uses on a kind of vacuum freeze drier shelf, belongs to the vacuum freeze drying and the drying equipment machine-building manufacture field of liquid state or solid-state food, medicine, biological products etc.
Background technology
Vacuum freeze drier is divided into medicinal freeze dryer, food freeze dryer, small test with three types freeze dryer.The characteristics of medicinal freeze dryer are that goods are generally all accomplished pre-freeze, insulation, the whole technical process of lyophilization on the shelving in same drying box.Because same group of shelf should possess refrigeration and realize again heating; So generally all adopt intermediary to conduct indirectly; Shelf temperature is inhomogeneous to cause with the not good problem of pallet heat conduction that energy consumption is big, technical process is long, do not reach problem such as product design residual water content standard is a crucial factor that troubles the pharmacy corporation development for a long time; Freeze dryer is general all raw material is contained in the pallet of placing in the pallet on the shelf freeze, the processing of lyophilization, parsing-desiccation; The thickness of pallet should be considered cold and hot distortion, therefore can not be too thin, generally about 1.5 ㎜; Be equipped with about the cillin bottle or the about 10-15 ㎜ of food splendid attire height in pallet of medicine, temperature is delivered to the tray bottom by the cold and hot temperature of shelf and begins till freezing topmost, lyophilization, parsing-desiccation article.But owing to be equipped with about the about 10-15 ㎜ of cillin bottle, medicine, biological products or food splendid attire height in pallet of medicine, the transmission of temperature needs the long period, again because shelf temperature is inhomogeneous; Caused the freeze-drying prods moisture content inhomogeneous; The qualification rate of product residual water content is influenced, and the pallet of making on the shelf is made by stainless steel material, when freeze-drying, is expanded with heat and contract with cold for a long time and can deform; So each producer has all spent great amount of manpower and financial resources; As from the flatness of shelf surface, surperficial plug welding point position, intermittent weld produced expands with heat and contract with cold and material or the like problem, variety of issue all can directly influence the heat-conductive characteristic between shelf to goods and pallet, causes the uneven temperature reason maybe; Therefore; Often have the interior residual water content of freeze-drying bottle of some user's reflections inconsistent, what have differs greatly, and does not reach product design residual water content standard.But use drawer type tray frame or bottle in bulk during the user's freeze-drying bottle that has; So very waste is feeded and the discharge time; Damaged easily again when loading and unloading material medicine bottle, begun to use the pallet that aseptic thin-film is shaped now abroad but price is high, damage easily, service time defective such as length.
Summary of the invention
The utility model is the pallet that uses on a kind of vacuum freeze drier shelf; Be the pallet that uses on a kind of simple in structure, manufacturing expense is low, accommodation is extensive, thermal conductivity is strong vacuum freeze drier shelf, mainly be provided with inside casing, housing and tray bottom and combine, in the middle of tray bottom is pressed on by inside casing and housing; What inside casing and housing adopted is corrosion resistant plate or aseptic plastic; What tray bottom adopted is stainless steel cloth, stainless sheet steel, aseptic plastic film or strong fiber, because tray bottom thickness is merely 0.15～0.8 ㎜, has good pliability again and can keep large-area with shelf surface and contact; So the temperature transmission far surpasses the stainless steel pallet; Cold and hot can very soon material thoroughly being freezed from the inside to the outside, in like manner, in temperature-rise period; The gasification of material is also quicker than traditional freeze dryer, the influence that tray bottom is not expanded with heat and contract with cold.Therefore can reduce freeze-drying time greatly, output has just obtained significantly to promote the also removable pallet of tray bottom.Having made full use of can be former, and residual water content is consistent in the freeze-drying bottle, can be applicable to that liquid state or solid-state food, Chinese and Western medicinal material, chemical industry, agricultural byproducts etc. carry out dry or cryodesiccated different processing purpose processed.
The purpose of the utility model is to realize through following technical scheme:
The utility model is the pallet that uses on a kind of vacuum freeze drier shelf; Pallet is provided with inside casing (1,3,5), housing (2,4,6) and tray bottom (7) and combines; It is characterized in that: inside casing of pallet (1,3,5) and housing (2,4,6) can be made rectangle or circle; Inside casing of pallet (1,3,5) and housing (2,4,6) have certain gradient; Inside casing (1,3,5) and housing (2,4,6) need closely cooperate; Tray bottom (7) is pressed on the centre by inside casing (1,3,5) and housing (2,4,6), and what inside casing (1,3,5) and housing (2,4,6) adopted is corrosion resistant plate or the aseptic engineering plastics that certain intensity is arranged, and tray bottom (7) adopts good stainless steel cloth, stainless sheet steel, aseptic plastic film or the strong fiber of thermal conductivity; Tray bottom (7) is also replaceable; Tray bottom (7) thickness is between 0.15～1.0 ㎜, has good flexible material, can keep the pallet that uses on a kind of vacuum freeze drier that maximum area contacts and the drying machine shelf with shelf surface.
The inside casing (1,3,5) of the pallet that uses on above-mentioned a kind of vacuum freeze drier shelf and housing (2,4,6); It is characterized in that:, can according to circumstances make a reinforcement at the upper, middle and lower different parts of inside casing (1,3,5) and housing (2,4,6) in order to increase the intensity of inside casing (1,3,5) and housing (2,4,6).
The utility model is the practical technical scheme of science of groping to sum up out through long-term practice, and it has advantages such as simple in structure, good energy-conserving effect, operating cost are low.
