Concentration method and device for traditional Chinese medicine extracting solution

Abstract

The invention discloses a concentration method and device for a traditional Chinese medicine extracting solution, which eliminate vacuum leakage, reduce the working amount, make production be more ordered and can find out failure reasons more quickly and conveniently. According to the technical scheme, the concentration method sequentially comprises the following steps of: (1) starting an automatic water supplementation valve to automatically supplement water to a buffering tank, so that a water feeding pipe in a recycling tank is lower than a liquid level in the tank, and the buffering tank contains water; (2) then starting fed liquid concentration equipment, detecting the flow of a liquid feeding pipeline through an electromagnetic flowmeter, transmitting the flow to a controller, judging whether a liquid feeding valve on the liquid feeding pipeline is open or closed according to the flow by the controller, and supplementing liquid to a concentration pot; and (3) when the concentration pot concentrates liquid, after a heat exchanger exchanges heat of the liquid, controlling an automatic valve and a condensed water discharging pump by the controller to enable condensed water from the heat exchanger to be mixed with condensed water from a roof evaporation type condenser and then to be fed into the recycling tank. The concentration device belongs to the technical field of concentration equipment.

Description

technical field [0001] The invention discloses a concentration method and a device, in particular to a method and a device for concentrating a traditional Chinese medicine extract, and belongs to the technical field of concentration equipment. Background technique [0002] There are many kinds of Chinese herbal medicines, which have a wide range of pharmacological effects, and their curative effects are increasingly valued in the world today, so they have broad development potential, and more and more people are devoted to the research and development of Chinese herbal medicines. To realize the medicinal value of traditional Chinese medicine, the extraction and concentration process of traditional Chinese medicine and its equipment are crucial to the research and development of traditional Chinese medicine, which directly affects the extraction rate of active ingredients of medicine, the utilization rate of medicinal materials and the economy. [0003] In the prior art, the ...

Problems solved by technology

However, in the production process of actual technology, the following situations usually cause vacuum leakage and abnormality: 1. The liquid in the liquid inlet tank is relatively small, and the liquid inlet pipe will be short of liquid and will suck in air to directly destroy the vacuum degree in the tank; 2. During the condensation process, if the water seal buffer tank at the front end of the condensate recovery tank is short of water, and the 10m water column of the condensate water pipeline is not sealed, the vacuum leaks; 3. The cooling water of the condensate drainage pump is forgotten to open, causing the machine seal Wear and tear, resulting in vacuum leakage; 4. The vacuum pump, fan, and cooling...
