Abstract

A microwave vacuum drier of extract consists of a tank of a microwave vacuum heater, a feeding and discharge door, a control cupboard of an electrical device, a microwave generator, a plastic container for holding the extract, a buffer tank, a rebound valve, a vacuum pump, a steam separator, a drain pipe, an air admission valve, a tube valve of pollution discharge, an equipment rack and connecting pipes. The microwave generator is positioned on the top and at the side of the tank of the microwave vacuum heater, one end of the tank of the microwave vacuum heater is arranged with the feeding and discharge door, while the top is connected with a vacuumlead. The plastic container for positioning the extract is arranged in the tank of the microwave vacuum heater. The whole body after combination is arranged on the equipment rack. The vacuum pipe is connected with the buffer tank, the rebound valve, the vacuum pump and the steam separator. When the drier works, the produced condense water is drained through the valve of pollution discharge. The air admission valve is used to reduce the vacuum degree in the tank of the microwave vacuum heater and the control cupboard of the electrical device is positioned at the right side of the equipment. The equipment has the advantages of fast drying speed for the extract, high drying quality, low investment, 80 per cent energy saving than the traditional drying devices, and no environmental pollution. The equipment can also be used for cryodrying of pasty foods like beef paste, meat paste, minced chicken and other goods.

Description

The medicinal extract microwave vacuum dryer

The utility model relates to a kind of (Chinese medicine) medicinal extract microwave vacuum dryer can carry out quick low temperature drying to (Chinese medicine) medicinal extract and handle within a short period of time, and can be used for lotion class material drying such as meat pulp.(annotate: Chinese medical concrete is by methods such as steaming, boil, endure, with the paste body shape material of the concentrated back formation of the effective ingredient in the medicinal material with Chinese medicine)

Background technology

At present, Chinese medical concrete mainly is to adopt oven drying, conventional vacuum drying and three kinds of methods of spray-drying, and these methods are traditional heating mode, and heat is to be undertaken by the mode of conduction, radiation, convection current, and the baking temperature of medicinal extract is generally all surpassed 80 ℃.Because medicinal extract viscosity is big, steam permeability is poor, need the time long with the Electric heat oven drying, under vacuum environment, the heat transmission is very difficult, particularly when the reduction of medicinal extract appearance moisture content, form solid shell, and center moisture content is still under the condition with higher, its internal moisture is difficult to continue to be evaporated, therefore, oven method needs the time more than 7 days medicinal extract could be made a good job of, and the conventional vacuum seasoning also needs the time more than one day, and the medicinal extract of these two kinds of method dryings is second-rate, yield poorly, energy consumption is very big, production cost is very high.Spray drying process is a kind of extract dry method that development in recent years is got up, it is that the medicinal extract that concentration is lower is injected into vaporific, adopt high temperature (generally adopting the temperature more than 100 ℃) to carry out the flow-type drying, owing to require dry medicinal extract concentration low (the high meeting of concentration plug nozzle), need the water yield of discharge big, this drying mode yields poorly, and energy consumption is big, equipment investment is big, and occupied ground is big.

Summary of the invention:

For overcome prior art to extract dry energy consumption height, yield poorly, the cycle is long, the investment big, cost is high shortcoming, the utility model provides a kind of medicinal extract micro-wave vacuum equipment, this equipment can carry out drying to medicinal extract at a lower temperature with in the short period equably, the dry mass height, energy consumption is low, equipment investment is little, and does not have any environmental pollution.

The technical scheme that its technical problem that solves the utility model adopts is: utilize microwave energy energy under vacuum state to transmit unaffected, medicinal extract self is heated fast, water evaporates, reach dry purpose, way is that medicinal extract is loaded in the plastic containers, place among the microwave vacuum heater, can adopt single or multiple container dress medicinal extract, single or multiple lift is put, medicinal extract is dry under the temperature of about 50C, just can extract dry is good in several hours, the steam that is produced during extract dry is extracted out by vavuum pump, in dry run along with the continuous minimizing of moisture content, the also corresponding reduction of microwave power, this drying mode be than the dry energy savings of traditional electric vacunm drying and Electric heat oven more than 90%, than spray-drying energy savings more than 80%.
