Microwave counter current continuous extraction apparatus

Abstract

The present invention mainly is relates to an extraction equipment used in the fields of food industry, pharmaceuticals industry and chemical industry. In particular, it relates to a microwave countercurrent continuous extraction equipment. It includes the following several portions: extraction drum, its oned end is equipped with feed funnel and extract outled, its another end is equipped with residuum outlet and extract inlet; on the extraction drum a microwave system is set, in the inner cavity of extraction drum a screw-type propeller is mounted, said screw-type propeller is driven by drive device. Besides, said invention also provides its working principle and concrete operation method.

Description

Technical field: [0001] The invention mainly relates to an extraction equipment used in industries such as food, pharmacy, and chemical industry, and particularly relates to the structure of a microwave countercurrent extraction device. Background technique: [0002] Various extraction devices are widely used in food, pharmaceutical, chemical and other industries. The traditional method is to add the extraction liquid to the extraction device, and conduct heat from the outside to the inside by heat conduction, heat radiation, etc., so as to realize the heating, concentration, and extraction of materials. Extraction, sterilization, etc. With the expansion of the application field of microwave technology, microwave extraction appears and develops rapidly. The basic principle is that the microwave penetrates the extracted material and reaches the internal microtube bundle and glandular cell system of the material. Due to the absorption of microwave energy, the internal tempera...

AI Technical Summary

Problems solved by technology

In this technical solution, since the solid-liquid transmission device obliquely extends into the cavity from the opening of the front wall, and protrudes from the opening of the rear wall, the cavity of the microwave heater is relatively large, and the amount of extraction liquid filled is relatively large. The final concentration is relatively low, which increases the difficulty of the next process

At the same time, the cavity is much larger than the transmission device, and the solid material is distributed in all the spaces of the cavity, which will inevitably form a dead angle, so that the extracted slag cannot be discharged in time; the suppressors installed at the inlet and outlet of the outlet lengthen the entire equipment The length of the useless part increases the cost of the equipment; there is no observation window on the cavity of the heater, so it is impossible to observe the in and out conditions of the extract and the color of the extract
