Problems solved by technology

The defects are as follows: first, high energy consumption; second, high-temperature sterilization (about 121 ° C), after the equipment is sterilized, it takes about 8 hours for natural cooling, and cooling to room temperature consumes energy; third, during high-temperature steam sterilization, The equipment produces vibration and shaking, and the sealing performance of the equipment is damaged; the fourth is that high-temperature sterilization accelerates the aging of valves and flange connection gaskets, and the sealing performance of the equipment is difficult to guarantee; fifth, the safety performance of high-temperature sterilization is poor
Sixth, defrosting, cleaning, and sterilization are carried out separately, wasting time and energy
It is difficult for ozone gas to enter the bacteria inside the dust particles by Brownian motion collision, the sterilization effect is weakened, and the chance of producing oxygen-resistant strains is relatively high

Embodiment 1

[0082] Implementation example 1: 5m 2 Examples of defrosting, cleaning and sterilization of freeze-drying units:

[0083] 1. Ozone gas generator selection:

[0084] 5m 2 Freeze-drying box for freeze-drying unit 4 volume V 1 = 1.5 cubic; condenser 5 volume V 2 =1.6 cubic, the pipeline volume that freeze-drying box 4 connects condenser 5 is V 3 =0.3 cubic, then the volume of the sterilization space is V=V 1 +V 2 +V 3 , that is, V=1.5+1.6+0.3=3.4 (cubic).

[0085] The amount of ozone generated by the ozone gas generator:

[0086] W 1 = 19.63 V 1 - 0.6225 = 19.63 × 3.4 1 - 0.6225 = 176.8 (mg / hour)

[0087] The above calculation is based on the theoretical amoun...

[0109] Implementation example two: 40m 2 Implementation example of three-in-one operation of defrosting, cleaning and sterilization of freeze-drying unit:

[0110] 1. Ozone gas generator selection:

[0111] 40m 2 Freeze drying unit Freeze drying box 4 volume V 1 18 cubic meters; condenser 5 volume V 2 It is 18 cubic meters, and the volume of the freeze-drying box 4 connected to the condenser 5 is V 3 is 0.5 cubic,

[0112] Then the volume of the sterilization space is V=V 1 +V 2 +V 3

[0113] =18+18+0.5

[0114] =36.5 (cubic).

[0115] The amount of ozone generated by the ozone gas generator 1-1:

[0116] W 1 = 19.63 V 1 - 0.6225 = 19.63 × 36.5 0.377

[0131] 60m 2 Freeze drying unit Freeze drying chamber volume V 1 is 24.5 cubic; condenser volume V 2 It is 20 cubic meters, and the volume of the freeze-drying box 4 connected to the condenser 5 is V 3 is 1 cubic meter,

[0132] Then the volume of the sterilization space is V=V 1 +V 2 +V 3

[0133] =24.5+20+1

[0134] =45.5 (cubic).

[0135] Ozone Gas Generator 1-1 Ozone Generation:

Abstract

The invention relates to a refrigerating drying machine, and method for using one solution to defrost, clean and disinfect. Wherein, said machine comprises a refrigerating drying tank, a condenser, a ozone preparer, a ozone water preparer, a defrost water heating and transporting device, and a clean compressed air input tube. The ozone preparer via tube is connected to the ozone water preparer; the ozone water preparer via tube is connected to the refrigerating drying tank and the condenser; the ozone water preparer has pure water, ejection water and feeding port; the defrost water heating and transporting device via tubes is connected to the refrigerating drying tank and the condenser; the clean compressed air input tube is connected to the drying tank and the condenser. The processes of defrosting, cleaning and disinfecting are processed in lower temperature with ozone water solution. The invention has better sealing property, saved time, and reduced energy consumption.

Description

technical field [0001] The invention belongs to a freeze-drying unit and its defrosting, cleaning and sterilization processes, in particular to a freeze-drying unit and its defrosting and cleaning processes which use the same solution to complete the three technological processes of defrosting, cleaning and sterilization in one step , Sterilization process. Background technique [0002] The function of the freeze dryer is to remove water or other solvents from frozen biological products by sublimation. In addition to obtaining long-term storage stability, freeze-dried biological products also retain other inherent biological activities and structures. The main part of the freeze dryer includes a freeze drying box and a condenser connected by pipelines and butterfly valves. Products for lyophilization are placed on shelves in a freeze-drying cabinet, and sublimated water or other solvents are collected in a condenser. After each batch of products is produced, the freeze dr...
