Description
Technical field
The utility model belongs to food processing equipment technical field, particularly relates to a kind of freeze drier.
Background technology
Freeze drying is exactly by hydrous matter, is first frozen into solid-state, then makes moisture wherein become gaseous state from solid state sublimation, preserves the method for material to remove moisture.Relative to drying, boil dry, dry, the conventional method such as spraying dry and vacuum drying, have the following advantages: dehydration is thoroughly, lightweight, be applicable to long-distance transport and preserve for a long time, at normal temperatures, adopting the vacuum packaging shelf-life can reach 3-5 years; Material is dry at low temperatures, and the heat-sensitive ingredients in material can be remained, and nutritional labeling and flavor loss are little, can the original composition of retaining food product, taste, color and luster and fragrance to greatest extent; Material is under low pressure dry, makes the unlikely oxidation deterioration of oxidizable composition in material, simultaneously because of the sterilization of hypobaric hypoxia energy or the vigor suppressing some bacterium.But current freeze drier air outlet manifold due to outlet air temperature low, as easy as rolling off a log condensation, be a kind of waste for low-temperature receiver, reduce the condensation effect of condenser system, and have great damage to equipment, impact uses continuously.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of freeze drier, comprise preposition condenser, air gun, moisture trap, automatic water trap, precooling regenerator, evaporimeter, device for drying and filtering, reservoir, compressor, described preposition condenser communicates with precooling regenerator and is provided with compressed air inlet, described moisture trap and precooling regenerator, evaporimeter communicates, its one end is provided with air gun, the other end is connected with automatic water trap, described precooling regenerator one end is provided with dry air outlet, the pipeline that described reservoir is connected with device for drying and filtering is provided with Pressure gauge, described device for drying and filtering is connected with evaporimeter by choke valve, the pipeline that described device for drying and filtering is connected with reservoir is provided with hot gas bypass valve, it is characterized in that: also comprise after-condenser, described after-condenser one end is connected with compressor, the other end is connected with device for drying and filtering.
The pipeline that described after-condenser is connected with device for drying and filtering is provided with high-low pressure protection switch.
The quantity of described high-low pressure protection switch is more than or equal to two.
Described compressor is hermetically sealed reciprocating compressor.
The beneficial effects of the utility model: the hot humid hot-air of the cold air after cooling and entrance carries out heat exchange, through the cold air of heat exchange because absorbing the heat lift of intake air temperature, simultaneously compressed air also through the refrigerant of the after-condenser of refrigeration system and high temperature again heat exchange the temperature of outlet is heated fully, guarantee that outlet air pipeline does not condense, take full advantage of the low-temperature receiver of outlet air simultaneously, ensure that the condensation effect of board refrigeration system, ensure that the quality of board outlet air, improve refrigerating efficiency, avoid condenser bad the brought high pressure chaser of heat radiation or mechanical disorder simultaneously, the motor of sealed compressor and compressor main body are sealed in a steel shell, and motor is in refrigerant gaseous environment and runs, and cooling condition is better, and the life-span is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
In figure: the preposition condenser of 1-, 2-air gun, 3-moisture trap, 4-automatic water trap, 5-precooling regenerator, 6-evaporimeter, 7-device for drying and filtering, 8-reservoir, 9-compressor, 10-compressed air inlet, the outlet of 11-dry air, 12-Pressure gauge, 13-choke valve, 14-hot gas bypass valve, 15-after-condenser, 16-high-low pressure protection switch.
Embodiment
