Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum precooling, in particular to a vacuum precooling device for fresh mushrooms. Background Art
[0002] The traditional cold storage preservation process relies on the air-cooled evaporator to exchange heat with the fresh mushrooms in the storage to achieve the purpose of cooling, and gradually cools from the outside to the inside. The temperature difference between the interior and surface of the fresh mushrooms is large and uneven, which will cause heartburn during use. The inside of the good surface has already rotted. Vacuum pre-cooling preservation is a physical preservation technology that relies on lowering the air pressure in the box to change the boiling point of water, so that the surface water and the internal free ion water of the fresh mushrooms evaporate and boil at low temperature, thereby taking away heat to achieve the purpose of cooling. The vacuum pre-cooling preservation process is different. Cooling is carried out under negative pressure. The surface water and the internal free ion water evaporate at the same time under negative pressure. The temperature difference between the inside and outside of the fresh mushrooms is small, reducing respiratory heat, thereby extending the shelf life and improving the preservation quality. The vacuum cooling technology is used to quickly cool the fresh mushrooms to a suitable storage temperature, which can inhibit the respiration of the fresh mushrooms, reduce nutrient consumption and microbial invasion, and thus extend the storage period of the fresh mushrooms.
[0003] Vacuum pre-cooling devices were developed as a result. In practice, a mobile carrier loaded with fresh mushrooms to be vacuum-cooled is pushed into the device from the inlet. Fixed rails located on the floor of the vacuum pre-cooling chamber keep the carrier in the center of the chamber, ensuring uniform vacuum cooling. However, since different production scales may require mobile carriers of varying sizes, the fixed rails cannot be flexibly adapted to these different sizes, causing some inconvenience.

[0029] Furthermore, the opposing surfaces of the two upper baffles constituting the guide rail are both inclined surfaces.

An air outlet 11 and a vacuum port 12 are embedded on the inner sidewall of the vacuum pre-cooling chamber 1 to meet vacuum pre-cooling requirements. The vacuum pre-cooling machine can be an existing product.
[0038] The vacuum pre-cooling chamber 1 is provided with an inlet port 13 on one side thereof, and two guide rails 15 are provided on the bottom plate 14 of the vacuum pre-cooling chamber 1, which are parallel to each other and spaced apart.

The specific implementation is as follows:
[0039] The bottom plate 14 is embedded with strip channels 141 perpendicular to the inlet direction. There are four strip channels 141 distributed on a group of opposite sides of the same square. Two strip channels on opposite sides share a guide rail.
[0040] The bottom plate 14 has a movable space below, within which a slide rail and a drive device 16 are located. The slide rail is parallel to the strip channel, and four parallel and vertically arranged baffles 17 are mounted on the slide rail. The baffles 17 are made of stainless steel and include an upper baffle 171, a connecting rod 172, and a lower connecting plate 173.
