Threshing is not clean: the reason. Feeding too much or feeding unevenly, the gap between the pattern and the concave plate is too large, the drum speed is too low, and the grain is too moist. Repair method. Reduce the amount of feed, even feeding; correctly adjust the threshing gap, the parts with serious wear should be promptly replaced; the belt of the power machine and the shell of the thresher should be reasonable, if the pulley slips, the tension pulley should be adjusted and the belt should be opened. Tight; stalks of wet grain should be properly ventilated and air-dried before threshing. Poor cleanliness of grain: the reason. Insufficient air flow from the fan, mostly fan belt drive slip, or because the fan pulley screw is loose, so that the fan speed can not reach the design index or the pulley idle. Repair method. Check the tightness of the fan drive belt and adjust the tension pulley appropriately. If the fan pulley fixing screw is loose, tighten it; reduce the feed amount or adjust the feed gap correctly. Excessive grain breakage: the reason. The threshing gap is too small or the drum speed is too high; the feed is uneven or the grain is too dry or too wet. Repair method. Check whether the threshing clearance is correct, and the minimum clearance for general threshing wheat should not be less than 4 mm; in addition, it is necessary to check whether the matching of the drum pulley and the power pulley is reasonable and accurate. If there is anything wrong, it should be adjusted or replaced. Excessive dust from the dust outlet: the reason. Exhaust volume is too large; pit holes are blocked. Repair method. Check whether the fan speed meets the requirements. If the diameter of the fan pulley is properly selected, if it does not meet the need to adjust; remove the blockage of the concave plate hole after power failure. Severe jams: the reason. The grain is too wet and the amount fed is too large; the drum speed is too low. Repair method. Appropriately reduce the amount of feed, and keep the feed evenly; check the motor power is sufficient or the voltage is too low; if the drum pattern is damaged, it should be promptly repaired; repair or replace the concave plate; adjust the tension of the feed chain, while checking the suction Dust fan belt tension and fan speed.
1.Good safety of gelatin-free.The first lyophilized Varicella Vaccine, containing no gelatin from animals, invented and produced in China. Getting rid of gelatin from varicella vaccine can significantly decrease the ratio of anaphylaxis incidence .
2.Long validity period by good stability. The first approved varicella vaccine with 36 months of validity period in the world. Adopting BH-2 stabilizer with own IP rights (Chinese patent granted No.: ZL200910138411.6, International patent application No.: PCT/CN2009/001405) greatly enhances the stability of the product and ensures the validity period for 36 months under the storage condition.

icacy. It`s documented that compared with the varicella vaccine of low titer, high titer vaccine can reduce breakthrough cases by nearly 75% in vaccination. Of all released batches of Varicella Vaccine from BCHT, the titers are not less than 10000 PFU/dose tested by National Institutes for Food and Drug Control.
