Abstract

The invention relates to a heat pump drying device, in particular to an inner circulation type heat pump drying device. The inner circulation type heat pump drying device comprises a compressor, a heat pump, a condenser, an evaporator, an expansion valve, an air pipeline and a drying chamber, wherein the compressor is connected to the evaporator by a line, the expansion valve is arranged on the upper part of the evaporator, and low-temperature air is transmitted to the drying chamber through the air pipeline. The inner circulation type heat pump drying device technology comprises the following steps of removing the moisture of damp and hot air in the drying chamber by utilizing the heat pump and reheating the dehumidified air, circulating the air to pass through the evaporator of the heat pump, cooling the moisture absorbed from the materials in the drying chamber to dew point to condense, exhausting the moisture out of the drying chamber; then, promoting the dehumidified air flowing forwards to the condenser, returning the heat absorbed from the air in the evaporator and the heat converted by the compressor by consuming power to the circulated air together by using the heat pump, wherein the present air has strong moisture absorbing capacity and drying capacity; then blowing the dried air back to the drying chamber by a blower to convect with the materials to take away the moisture in vegetables and dry the vegetables.

Description

Inner circulation type heat pump drying device
Technical field
The present invention relates to a kind of heat pump drying device, specifically relate to a kind of inner circulation type heat pump drying device, mainly be applicable to dehydration, the drying of vegetables, fruit, belong to refrigeration technology field.
Background technology
At present, along with socioeconomic fast development, flowing of employment worker constantly increases, people travel the picnic activity also increasing, the instant food particularly needs of vegetables is particularly outstanding, but the fresh-keeping of vegetables time is short, destruction nutrition apt to deteriorate, eat and deposit, carry all inconvenient, especially season dish, the local characteristic dish is sold in being difficult to be implemented on a large scale, eat, the fresh-keeping dish of supply is arranged on the market, the quick-frozen dish, the energy proper extension Vegetable Preservation time, but the vegetables mouthfeel after quick-frozen is relatively poor, and nutrient loss does not have good solution so far.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art part, a kind of inner circulation type heat pump drying device is provided, this device includes compressor, heat pump, condenser, compressor is connected with evaporimeter by circuit, expansion valve is arranged at evaporimeter top, and the low temperature dry air is transported to hothouse by air duct.Internal circulation type heat pump drying technology be utilize heat pump to remove in the hothouse moisture in the damp-heat air and make dehumidifying after air reheat, circulating air is by the evaporimeter of heat pump, the moisture that will absorb material in hothouse is cooled to dew point and condenses, and discharges outside the hothouse.Then, air after the dehumidifying flows forward and arrives condenser, heat pump will absorb heat that the heat of air and compressor consumed work transform again and transfer back in the circulating air more in the lump and go in evaporimeter, at this moment air has very strong moisture absorption and drying capacity, then, dry air is blown back in the hothouse and the material convection current by blower fan again, takes away the moisture in the vegetables, realizes the drying to vegetables.
The present invention is a kind of inner circulation type heat pump drying device of realizing with following technical scheme, it is characterized in that: this device includes compressor, heat pump, condenser, compressor is connected with evaporimeter by circuit, and expansion valve is arranged at evaporimeter top, and the low temperature dry air is transported to hothouse by air duct.
Described device includes compressor, heat pump, condenser, and compressor is connected with evaporimeter by circuit, and expansion valve is arranged at evaporimeter top, and the low temperature dry air is transported to hothouse by air duct, and described hothouse has exhaust piping.
Advantage of the present invention is: this apparatus structure is simple, reasonable, traditional open drying equipment is changed into closed internal-circulation type, and baking temperature is low, color, shape and health, the security of article have guaranteed to be dried, improved the added value of dehydrated fruits and vegetables, finished product behind dry processing is convenient to storage, transportation.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail:
Accompanying drawing is a structural representation of the present invention:
Among the figure: 1, compressor, 2, heat pump, 3, condenser, 4, air duct, 5, expansion valve, 6, evaporimeter, 7, hothouse, 7-1, exhaust piping.
The specific embodiment
As shown in the figure: a kind of inner circulation type heat pump drying device, this device includes compressor 1, heat pump 2, condenser 3, compressor is connected with evaporimeter 6 by circuit, expansion valve 5 is arranged at evaporimeter top, and the low temperature dry air is transported to hothouse 7 by air duct 4, and hothouse has exhaust piping 7-1.
The course of work: this device utilize heat pump to remove in the hothouse moisture in the damp-heat air and make dehumidifying after air reheat, circulating air is by the evaporimeter of heat pump, the moisture that will absorb material in hothouse is cooled to dew point and condenses, outside the discharge hothouse.Then, air after the dehumidifying flows forward and arrives condenser, heat pump will absorb heat that the heat of air and compressor consumed work transform again and transfer back in the circulating air more in the lump and go in evaporimeter, at this moment air has very strong moisture absorption and drying capacity, then, dry air is blown back in the hothouse and the material convection current by blower fan again, takes away the moisture in the vegetables, realizes the drying to vegetables.
