brewhouse with gas heating Standard operation and maintenance parameter 1.1 Design: Steam pressure ≤0.09Mpa evaporation capacity 300-600kg /h 1.2 Practice: steam pressure ≤0.09Mpa evaporation capacity 300-500kg /h.

1. Check preparation

Check the valves, appliances and instruments are in good condition. Fill in and hang up the running status card.

Ii. Operation

1, open the pump feed, add the material to the evaporation chamber second mirror 1/2, close the pump.

2. Open the steam valve, start heating, and open the distilled water return valve and condensate inlet valve.

3. Sample and analyze the distillate alcohol content, adjust the return valve, and open the discharge valve to put alcohol into the alcohol storage tank after the alcohol content is qualified.

4, according to the amount of alcohol in the evaporation chamber, timely add low-concentration alcohol, adjust the return valve after feeding.

5. When the alcohol content in the evaporation chamber is less than 5%, stop the distillation and open the drain valve to discharge the residual liquid.

6. After distillation, close the steam valve and cooling water valve.

7. Clean the equipment according to the cleaning procedures.

Third, maintenance

1, the distillation tower in the device, the material in the tower is very clean, no pollution, can be general inspection of its seal for many years, only when the distillation effect of the packing is significantly reduced for overhaul, it is necessary to disassemble the whole tower, take out the packing and replace the damaged packing and flange, and carry out the whole tower air tightness test.

2, the annual overhaul should be carefully cleaned the dirt in the heating room, and the evaporation of the indoor wall with a brush. brewhouse with gas heating Standard Operation and Maintenance Code No. SOP· 03/0014 Edition 2 Page No. 2/2

3, annual overhaul, chemical cleaning agents should be used to clean the outer wall of the condenser and cooler. 4.4 During overhaul, instruments and instruments should be checked and corrected to make them in good condition.

4, overhaul flange, valve, pipe fittings and other careful inspection, damage and failure in time to replace. 4.6 All thermal insulation layers in the device shall be checked during overhaul, and those damaged or invalid shall be replaced in time.
