Abstract
A negative pressure dehydration dryer for edible fungi comprises a drying chamber capable of being inclosed; a plurality of racks are arranged in the drying chamber; steam channels communicated with one another are arranged in the racks and are connected with a steam pipe; heat brought by steam can heat edible fungi placed on the racks; the drying chamber is connected with a vacuum pump; and the vacuum pump can pump out air in the drying chamber to reduce the air pressure in the drying chamber. According to the utility model, the air pressure in the drying chamber can be reduced through the vacuum pump so as to reduce the boiling point of water, and steam is used to heat edible fungi to enable the temperature to reach medium and low temperatures, so that the edible fungi can be dehydrated and dried quickly, and the phenomenon of oxidative browning does not occur; therefore, the condition and taste of dried edible fungi can be improved, and the product quality can be increased.
Description
Technical field
The utility model relates to a kind of edible mushroom drying equipment, specifically relates to a kind of edible mushroom negative pressure dehydrating drier.
Background technology
Known edible mushroom generally adopts the hot blast high-temperature baking to dehydrate, and is that the patent documentation of CN102080923A discloses a kind of edible mushroom sleeve baking room like publication number, and it comprises main house body; Access door is arranged on side wall; Steam heater and some oven dry bedsteads of some connection steam pipeworks are set in the house, on the oven dry bedstead, place some edible mushroom sleeve baskets, in the house, be installed into blower fan on the wall of an end; On the wall of the other end exhaust blower is installed in the house; It also comprises temperature controller, and the input of controller connects temperature sensor, and the output of controller connects the magnetic valve on the steam pipework.Though this technical scheme can realize the quick dewatering drying of edible mushroom; But the deficiency that exists is, edible mushroom is in hot environment in the process of dehydrating, and is prone to oxidation reaction takes place and causes browning phenomenon; Thalline darkens, and influences the article phase and the mouthfeel of dry edible mushroom.
Summary of the invention
The utility model provides a kind of edible mushroom negative pressure dehydrating drier, can carry out quick dewatering drying to edible mushroom at middle low-temperature space, and browning phenomenon does not take place in the process of dehydrating edible mushroom, and product article phase and mouthfeel are good, and quality is good.
The technical scheme that the utility model adopts is: a kind of edible mushroom negative pressure dehydrating drier; Comprise sealable hothouse; Hothouse is provided with many racks; Establish steam channel in the rack and be interconnected, and connect steam pipe, the heat that steam brings can be heated to the edible mushroom that is positioned on the rack; Hothouse connects vavuum pump, and vavuum pump can be extracted the air in the hothouse out, to reduce the hothouse internal gas pressure.
During work, the external steam pipe is sent into steam to rack steam inside passage, and the heat that steam brings can be heated to the edible mushroom that is positioned on the rack; And make it to be warmed up to 20-50 ℃ middle low-temperature space, after vavuum pump powered up work, the hothouse internal gas pressure reduced gradually; The outside relatively negative pressure that forms; The boiling point of water also descends thereupon in the hothouse, and after the boiling point of water dropped to the residing temperature province of edible mushroom, the inner moisture of edible mushroom left edible mushroom through being boiled into water vapour; Edible mushroom dehydrates rapidly, forms dry edible mushroom.In the process of dehydrating, edible mushroom is in the medium and low temperature zone all the time, and places the environment of the few oxygen of low pressure, and oxidation reaction does not take place thalline, can not cause browning phenomenon, and thalline dry product color is pure, and article phase and mouthfeel are good, and quality is good.
In the above-mentioned hothouse temperature sensing controller is set, steam pipe connects rack steam inside passage through adjustable valve, and temperature sensing controller is controlled the steam flow in the adjustable valve according to the temperature value in the hothouse.When dry indoor temperature was too high, temperature sensing controller control adjustable valve reduced steam flow, and the heat that steam brings reduces, and dry indoor temperature drops to suitable warm area thereupon; Cross when low when dry indoor temperature, temperature sensing controller control adjustable valve increases steam flow, and the heat that steam brings increases, and dry indoor temperature rises to suitable warm area thereupon.Dry indoor temperature remains on suitable warm area, helps the speed that dehydrates that makes having of edible mushroom suitable, and the oxidizing brown stain phenomenon can not take place again.
The utility model reduces the air pressure in the hothouse through vavuum pump; To reduce the boiling point of water; And utilize steam that edible mushroom is heated to middle low-temperature space, make the edible mushroom quick dewatering drying, and the oxidizing brown stain phenomenon can not take place; Help improving the article phase and the mouthfeel of dry edible mushroom, improve the quality of products.
Description of drawings
Fig. 1 is the example structure sketch map of the utility model.
The specific embodiment
Below, be described further in conjunction with the embodiment of accompanying drawing the utility model.
Fig. 1 shows a kind of edible mushroom negative pressure dehydrating drier; Comprise sealable hothouse 1, hothouse 1 is provided with many racks 2, establishes steam channel in the rack 2 and is interconnected; And connecting steam pipe 3, the heat that steam brings can be heated to the edible mushroom that is positioned on the rack 2; Hothouse 1 connects vavuum pump 4, and vavuum pump 4 can be extracted the air in the hothouse 1 out, to reduce hothouse 1 internal gas pressure; Temperature sensing controller 5 is set in the hothouse 1, and steam pipe 3 is through the steam channel of adjustable valve 6 connection racks 2 inside, and temperature sensing controller 5 is controlled the steam flow in the adjustable valve 6 according to the temperature value in the hothouse 1.
