Description

Continuous loading and unloading device of freeze-drying equipment

Technical Field

The utility model relates to a freeze-drying equipment especially relates to a unloader in succession of freeze-drying equipment.

Background

Vacuum freeze drying equipment, or freeze drying equipment for short, is to freeze food, medicine and other material below the eutectic point temperature to change the water content into solid ice, and then to sublimate the ice into water vapor in vacuum environment, and then to condense the water vapor with a water catcher to dry the product. The patent application No. 201510017464.8 in China, shown in fig. 1 and fig. 2, discloses a vacuum freeze-drying device for processing food, which comprises a bin body 1, wherein vertical side brackets 12 are fixed in the bin body, the brackets extend out of heating shelves 13, an accommodating interval of a skip 14 is formed between the heating shelves at two sides, the skip comprises a vertical suspension 42, a horizontal tray 43 extends out of the vertical suspension, and when the skip is pushed into the bin body, the horizontal tray on the suspension of the skip is just positioned between two adjacent horizontal heating shelves. During processing, food materials to be freeze-dried are spread on the material tray and then transferred to the skip car, and are conveyed into the bin body 1 by means of the hanging skip car hung on the hanging rails 1-4. According to the heating volume of the bin body, materials with corresponding quantity can be sent into the bin body for vacuum drying at one time, all the materials are cooled through the quick-freezing tunnel, the temperature of the materials is lower than the eutectic point of the materials, and then the vacuum drying process is adopted, so that the moisture in the materials is directly sublimated into gaseous state from the solid state to be rapidly evaporated. The formed freeze-dried product is spongy, has no drying shrinkage, good rehydration property and extremely low moisture content, maintains the original structural performance and nutritional ingredients of the product, and can be preserved and transported for a long time at normal temperature after being correspondingly packaged.

However, the freeze-drying apparatus shown in fig. 1 and 2 firstly needs to use the skip car to send the material to be freeze-dried into the vacuum drying chamber, and the clearance height of the skip car is high, and the operator needs to put the tray into the upper position of the skip car, so the difficulty of loading and unloading the material is considerable. Secondly, when loading and unloading the charging tray to the skip, the left and right sides of the skip need to be loaded and unloaded evenly to ensure the steady state of the skip, prevent the skip from inclining and causing the charging tray to fall off. Moreover, when the hanging skip car is conveyed into the bin body 1 by means of the hanging rails 1-4, the bottom of the skip car is not provided with a fixed structure and is easy to shake, so that potential hazards are brought to safe operation. In addition, the depth of the vacuum drying bin of the conventional freeze-drying equipment is about more than ten meters, and the internal space is long and narrow, so that a skip car needs to be pushed into the quick-freezing tunnel and the equipment, and the labor intensity of operators is enhanced. In summary, the conventional freeze-drying equipment has no continuous processing capability, and it needs to feed all the materials into a vacuum drying chamber at one time and then start a heating and drying process, and because the equipment is started, preheating and precooling processes are performed, energy waste of the whole equipment is caused.
