Respectively in this paper, the use of fermentation tank and maintenance methods of fermentation tank

Hangzhou Huihe Equipment Co. Ltd:2013-11-26

The fermentation equipment is widely used in dairy products, food, biological engineering, beverage, wine industry such as mixing and fermentation.

This article is mainly explained the use of fermentation tank and maintenance methods of fermentation tank as follows:

The using methods of fermentation tank

1. Open machine

a. Fermentation tank equipment status flag state for using;

b. Start the mixing control key button.

2. Usage

a. Air filter sterilization;

b. Close air inlet valve, open vent valve, all for pressure drop to zero;

c. Open fermentation tank steam into the steam valve, exhaust valve 1/4 turn, the pressure is 0.2Mpa, in the real tank fermentation;

d. Stainless steel fermentation tank steam in valve, air filter in tank valve, sampling tube into the tank valve, endoscopic valve, vent valve, unscrew the cap, pass into the steam booster, heating up;

e. Internal pressure rise 0.12 0.14 Mpa, temperature rise as to timing starts 120 celsius to 124 celsius, 30 min sterilization;

f. The sterilization process at any time adjust the inlet and exhaust valve regulated, and the original record

3. Stop machine

a. After sterilization, close the air filter, into the tank valve, steam valve, open the air intake valve and exhaust valve will filter medium dry;

b. Closed fermentation tank inlet steam valve, the sampling tube, into the tank valve, tighten the vaccination flap;

c. Open fermentation tank cycling water in valve, water out valve, cool down;

d. Internal pressure reduce to 0.5 Mpa, the temperature dropped to 50 celsius to 60 celsius, Stop stirring power control button , stop stirring;

e. Open air filter into tank valve 1/4 circle, exhaust valve opening 1/2 circle, stir into the air to cool, good control the air flow, to prevent a bubble cap;

f. Inner temperature dropped to 38 celsius to 40 celsius, the notification mold post inoculation;

g. Pay to see can post according to the technological requirements for temperature control training; N > $Nw4.4.8 equipment status flag for the proper state.

4. Cleaning and disinfection

Pay attention to the execution of fermentation equipment cleaning and sanitation standard operating procedure, it should fill in the corresponding records.

Fermentation tank maintenance methods

1. Anti-corrosion

2. To protect the outer wall of fermentation tank, prohibit with acid alkali cleaning;

3. Paint layer and protective layer falls off area shall not be greater than the sum of the total area of 5%, otherwise it should be in accordance with the regulation on medical equipment, piping color requirement, besmear again (processing);

4. Stirring, shaft seal, air and steam pipe, valve and thermal insulation layer of mark color shall be intact;

5. The outer wall of fermentation tank, steam valves shall, from time to time derusting points clearly.

6. It should be conducted on a regular basis and steam trap valve and check, if any, should be replaced in a timely manner.

7. Before and after second open steam bypass valve should be completely open, will be condensed water tanks interlayer completely after all, it can normal control.

8. Tanks for inspection, check crack, welded body falls off, etc

9. For turbine, vortex rod lubrication on a regular basis.

10. Half a year of shaft for cleaning, or replacement bearings, add grease.

11. Prohibit the equipment with hurt and sickness, should always pay attention to the instrument precision quantity whether accord with production requirement, and check regularly.
