Abstract

The invention discloses a cold and hot integrated vacuum freeze dryer. The cold and hot integrated vacuum freeze dryer includes a dry bin, a shelf, a cold trap, an acrylic plate, a regulating valve, arefrigeration and heating all-in-one machine, a vacuum pump and a control system; a frame is of a main body outer frame structure, a touch screen is installed on a frame panel, and the control systemis installed inside the fame; the dry bin is connected with a dry bin acrylic plate; the shelf is installed inside the dry bin; a cold trap communicates with the dry bin through a vacuum degree regulating valve and is connected with a cold trap acrylic plate at the same time; a door knob is installed on the dry bin acrylic plate and the cold trap acrylic plate; the vacuum pump is connected with the cold trap; a refrigeration and heating all-in-one unit is connected with the cold trap through a cold trap refrigeration pipeline, and a shelf refrigeration and heating pipeline is connected with the shelf. The cold and hot integrated vacuum freeze dryer is compact in structure, convenient to operate, and good in temperature uniformity, one-button automatic operation and the vacuum degree control function can be realized, the intelligent level of cold and hot integrated vacuum freeze dryer is improved effectively, and the operative difficulty index of operating staff is reduced sharply.

Description

technical field [0001] The invention belongs to the technical field of medicine and food machinery, and relates to a novel vacuum freeze-drying equipment. Background technique [0002] Vacuum freeze-drying (referred to as freeze-drying) is to freeze the material below the eutectic point temperature to make the water into solid ice, and then directly sublimate the water in the material from solid to gaseous state by vacuuming and discharge it out of the material. a drying method. Usually, the vacuum freeze-drying process mainly includes: pre-freezing stage, sublimation drying stage and analytical drying stage. [0003] Moreover, as the amount of food refrigerated is increasing day by day, its complex distribution system and the shortcomings of easy mixing of germs make people need a method that does not require refrigeration, is easier to store, and can keep fresh for a long time. Vacuum freeze-drying technology caters to this this need. Freeze-dried food is light in weigh...
