Embodiment 1

[0015] A vacuum-assisted preparation process of dried leeches, the preparation process has the following steps:

[0016] (1) Place a layer of high-density plastic film 1 on the platform 3, and place the tray 4 on the film 1. The tray 4 has evenly distributed arc-shaped grooves, and the grooves have matching grooves. The briquette, the length and width of the film-1 are greater than the tray 4;

[0017] (2) Lay the adult leeches in the groove, press the block to keep the leeches in a flat state, place a layer of high-density plastic film 2 on the upper surface of the tray 4, and seal the film 1 and the film 1 with the sealing strip 5 The film two 2 is sealed and bonded, and the film two 2 has an air outlet, and the air outlet is connected to the inlet of the vacuum pump 6 through a pipeline;

[0018] (3) Turn on the vacuum pump 6 to quickly reduce the space between film one 1 and film two 2 to a constant value, keep the reading of the vacuum gauge at 0.01-0.5 atm for 5 hours, ...

Abstract

The invention relates to a vacuum-assisted preparation technology of dried leech products. The technology comprises the following steps: sequentially placing a first plastic film and a pallet on a platform, spreading adult leeches in a groove in the pallet, pressing with a press block to maintain the spread state of the leeches, placing a second plastic film on the upper surface of the pallet, carrying out sealing bonding of the first film and the second film by using a sealing adhesive strip, opening a vacuum valve on a vacuum pump to rapidly reduce a space between the first film and the second film to a constant value, and maintaining the value of a vacuum meter between 0.01 and 0.5atm for 4-6h to make the adult leeches become the dried leech products. Compared with the prior art, the vacuum-assisted preparation technology is simple, allows the leeches to be spread through the arrangement of the press block in the groove, avoids the formation of a curled state of the leeches during the sudden meeting with the inspiration of the vacuum pump, and allows the finally obtained dried leech products to have a flat fusiform, so the post-treatment is convenient, and the technology is suitable for the large scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of processing dry leech products, in particular to a vacuum-assisted preparation process for dried leech products. Background technique [0002] Leeches, commonly known as leeches, horse turtles or inner drills, belong to the phylum Annelida. There are more than 500 kinds of leeches discovered in the world. Leeches in natural conditions usually live in freshwater lakes, rivers, ponds, ditches or rice fields. The more common leeches are scientifically called broad-bodied golden leeches. This kind of leech does not suck blood, but mainly feeds on the body fluids or soft tissues of invertebrates, such as larvae or plankton of aquatic insects such as snails and river mussels. Sometimes they also feed on Humus in water surface or shore soil. Leech is a traditional special medicinal aquatic animal in my country. Its processed dried products have the effects of treating stroke, high blood pressure, clearing fatig...
