Sealing device for continuous vacuum pressure material feeding and discharging processing

Abstract

The invention pertains to such mechanical equipments processing fields as foods, traditional Chinese medicine material, chemical engineering, timber, etc, relating to a sealing device that can keep vacuum degree / pressure even when materials continuously come in and go out. The device consists essentially of a sealing device shell, a rotatary drum, a swaying cylinder, a material inlet, a pre-vacuum inlet, and a material outlet. The device can match all kinds of processing equipments with different internal shapes to realize continuous vacuum / pressure and process different kinds of products, such as different processing technique requirements of low temperature drying and freezing, low temperature extraction, disinfection, fresh keeping, thawing and reheating, rubber vulcanization, etc.for such products as foods, tea, traditional Chinese medicine material, chemical engineering, timber, etc. The device can also process the packed material, fragmentary material, and staple material, etc. with high temperature water bath of saturated steam in a processing warehouse, to achieve the requirement of high quality, high efficiency, highly energy conservation and time saving, furthermore, better meet environmental protection requirement.

Description

technical field [0001] The invention belongs to the field of mechanical equipment processing of food, Chinese medicinal materials, chemical industry, wood, etc., and relates to various processing equipment configured with a sealing device capable of maintaining vacuum degree / pressure under the condition of continuous feeding and discharging of materials. Background technique [0002] There are multiple forms in the existing literature records, such as U.S. patents: 3812775, 4059046, 4844931, 4852475, 5182982, 5988051; European patents: 0409643A, 58183048A; Chinese patents: 94243431, 01234613, etc. The sealing devices of the continuous vacuum inlet and outlet material processing in the literature have their own characteristics. Although the methods are different, their structures all adopt the gate type or the inlet and outlet sealing processing devices with a decompression transition. The structure is complex and the processing accuracy is high. The requirements are high, th...

[0002] There are multiple forms in the existing literature records, such as U.S. patents: 3812775, 4059046, 4844931, 4852475, 5182982, 5988051; European patents: 0409643A, 58183048A; Chinese patents: 94243431, 01234613, etc. The sealing devices of the continuous vacuum inlet and outlet material processing in the literature have their own characteristics. Although the methods are different, their structures all adopt the gate type or the inlet and outlet sealing processing devices with a decompression transition. The structure is complex and the processing accuracy The requirements are high, the manufacturing cost is high, and it is difficult to achieve high vacuum / pressure stability, and various equipments have different processing requirements for different material types, shapes, and purposes, all of which have certain limitations and are very difficult to promote. It is very difficult, and gap-type vacuum processing equipment is used in the existing equipment, so the cost of processed products is high, and energy waste is large. The use of normal pressure continuous processing also reduces product quality for some volatile products, thus affecting the scope of product processing.
