Abstract
The utility model discloses low-temperature vacuum drying equipment, which comprises a drying system, a vacuum system and a heating system. The drying system comprises a box with a sealing door, a hot water pipeline is wound in the box, and a thermometer and a vacuum meter are mounted in the box. The vacuum system comprises a condenser, a liquid storage tank and a vacuum pump which are sequentially connected with the box. The heating system comprises a circulating water storage tank, an electric heating device and a steam heating device, the circulating water storage tank is connected with the hot water pipeline in the box through a water pump to form a circulating system, and the electric heating device and the steam heating device are used for heating circulating water. The low-temperature vacuum drying equipment is applicable to thermally sensitive materials easy to decompose, polymerize and deteriorate at high temperature, and is capable of recycling organic solvents.
Description
Technical field
The utility model relates to a kind of low-temperature vacuum drying equipment.
Background technology
In pharmaceutical manufacturing, tend to production operation through super-dry, so that keep the cleannes of article to be dried, make it reach the qualified requirement of moisture.Dry water-containing materials mainly uses electric heating blast drier, freeze drier etc.The general baking temperature of hot-air drier is higher, has oxygen to exist in the dry run, and is bigger to the quality influence of dry medicine; Freezing dry process was divided into for two steps: the freezing and lyophilization of product; Freeze generally to make the water in the product become little ice crystal below-20 ℃, sublimation stage pressure must carry out below the pressure (627pa) of three phase point; Freeze drying can keep the original form of dry products; Reduce the loss of bioactivator to greatest extent, but drying time long (generally needing 15-22 hour), energy consumption is big.
The utility model content
The utility model provides a kind of equipment that can in low temperature range, carry out the lower low-temperature vacuum drying of rapid draing and energy consumption, is applicable at high temperature to be prone to decomposition, polymerization and rotten heat sensitive material, recyclable organic solvent.
A kind of low-temperature vacuum drying equipment comprises drying system, vacuum system and heating system; Drying system comprises the casing 1 of being with hermatic door, coiling hot water pipeline 2 in the casing, casing mounting temperature meter 3 and vacuum meter 4; Vacuum system comprises condenser 5, fluid reservoir 6 and the vavuum pump 7 that is connected with casing 1 in order; Heating system comprises recirculated water storage tank 8, connects into the circulatory system through water pump 9 and casing 1 interior hot water pipeline, also comprises electric heater unit 10 and steam heater 11, heats to recirculated water.
Use the method for above-mentioned low-temperature vacuum drying equipment, mainly may further comprise the steps:
(1) sample to be dried is put into casing and closed hermatic door.
(2) open electric heater unit or Steam Heating heater in the recirculated water fluid reservoir, water be heated to assigned temperature, water pump with hot water through in the embedded pipeline of material disc in the circulating water inlet road suction casing.
(3) open vavuum pump, with being evacuated in the casing, the double action through embedded ducted hot water of material disc and vacuum converts the water in the material into steam, and steam is by in the condenser fluid reservoir below the vavuum pump suction condenser.
(4) hot water in the casing flows out casing through the embedded pipeline of material disc, and gets into heating once more in the recirculated water fluid reservoir through the circulating water inlet road.
(5) close electric heater unit and steam heater, vavuum pump, the water pump of recirculated water fluid reservoir; Atmospheric valve above the box sealing door is opened; When treating that temperature dial plate displays temperature in the casing front door panel is to room temperature; After pressure in the pressure dial plate dropped to safe range, the opening encapsulation door took out dried material.
It is case structure for the present invention, and its advantage is to utilize the vavuum pump dehumidifier of bleeding, and has accelerated rate of drying; The boiling point of material solution reduces under the vacuum; The driving force of heat transfer of evaporimeter is increased, therefore can save the boil-off gas heat transfer area to certain heat output, the thermal source of evaporation operation can adopt electrical heating or Steam Heating; The evaporimeter heat loss is little; No any impure sneaking into belongs to static vacuum desiccator in the dry run, so the body of dried material can not damage.
