IMPa pressure for 30 minutes, then placed in a 45 drying oven, and the water in the paraffin was evaporated for more than 3 days. The test tube with the screw cap was used to make the wort slope, and the original seed that had just rejuvenated was picked up on the inclined surface and cultured for 25 days for 25 days. Add paraffin to the slope, liquid paraffin is more than 1 cm above the slope, and stored in a refrigerator of 2-4. The preserved strains are transplanted once every 12 years. The test results show that the liquid helium preserves the yeast survival compared with the ordinary slope. The sac is the first book of the year. (China Resources Yanhua Beer Co., Ltd. 114041 The original design of the saccharification filter tank waste system of our factory adopts the spiral conveying waste and compressed air pipeline blowing. The method is to transport the wheat grains to the pipeline 400 meters away. The wheat grains are screwed to the compressed air blow pipe, and the compressed air blows the wheat grains into a dough, and the wheat grains are transported to the discharge through the waste pipe. The compressed air is controlled to be opened and closed by a pneumatic valve. During the process of discharging the pneumatic valve, the pneumatic valve is always in the open state, and the compressed air is directly blown to the draining pipeline. After a period of operation, we found that there are some shortcomings: 1 the compressed air pressure is not well controlled, the pressure value is too large, it is easy to blow the mess, causing a large amount of compressed air to leak, and the row is slow, the time is too long; 2 compression The air pressure value is too low, which makes the transportation of the bad group difficult, and it is easy to block the material. Similarly, the time of the mess is longer; 3 If the distiller's grains contain more water, it is difficult to form a bad mass during the air pressure purging, which causes difficulty in transportation; 4 Due to the long time of the mess, the compressed air is seriously wasted, and the motor reducer of the screw conveyor consumes electric energy, resulting in long time and high energy consumption. According to the above situation, we have improved the bad system. First, add a time relay (as shown) to the solenoid valve that controls the pneumatic valve to make the solenoid valve play periodically. The sequence of actions is: 1 the solenoid valve is open, the pneumatic valve is open, the compressed air begins to blow; 2 the solenoid valve is closed, the pneumatic valve is closed, and the compressed air stops purging. The process time is 3 seconds and 10 seconds. This changes the opening and closing of the pneumatic valve, so that the compressed air intermittently sweeps the exhaust pipe, and the spiral can push the distiller's grains to form a bad mass in the compressed air, and also prevent the leakage of the empty air in the compressed air. The cost of retrofitting is very low, just buy a time relay. W-switch relay pneumatic valve 1 row of bad retrofit electrical principle circle through actual production inspection, it takes 2 hours before the transformation, only 1 hour after the transformation, if plus the intermittent time of the solenoid valve in the production process (about 0.23 hours), A total of 1.23 hours of compressed air supply was reduced, saving 61.5% of compressed air, and the medium-rotating motor and air compressor motor operated for less than one hour, saving about 50% of power consumption. Undoubtedly, the energy-saving effect is obvious.
