Note: Yi Kean buy is in sterilization craft from after handing in, watery fluid heats through board type heat exchanger, warm up to 100 ~ 105 ℃ , maintain 15min. By a type machinery that lays charcoal layer via already besmearing the rare sugar of high temperature sterilization press is had filtering decolour. Activated carbon (wet) add a quantity to be 1.0%/t dry basis.

(12) , crystallization adjusts thick syrup chroma 72 ~ 74% , 62 ℃ of 60 ~ , PH is worth temperature 3.8 ~ 4. 2 wait after reaching target, send crystallization canister directly. Crystallization canister reserve seed for planting 25 ~ 30% , the mixed liquor temperature that thick syrup and brilliant plant when canful should ≥48 ℃ . Crystallization drops in temperature the curve is: Crystallization total time 60 hours. Raise brilliant 12 hours, use nature to drop in temperature law. Refrigeration crystallizes 48 hours, divide a level. The first paragraph 28 hours, candy lukewarm fall from 46 ℃ 35 ℃ , drop in temperature hourly ≤0.4 ℃ ; The 2nd paragraph 20 hours, candy lukewarm fall from 35 ℃ 22 ℃ , drop in temperature hourly ≤0.65 ℃ . Cooling water of crystallization canister interlining is warm ≤15 of as lukewarm as candy difference in temperature ℃ . Mixing speed is crystallization canister 3min/360° . Crystallization canister and give divide evenly of makings system equipment to be obturator, compress air to maintain by asepsis show inside container controlling state. Crystallization receives rate massecuite dry basis / wet candy dry basis is 53% .

(13) when dividing honey of sweet centrifugal cent, strong water catharsis is operated, mother liquor swings 4 ~ 6 minutes, pour water 5 times next, every time catharsis wet candy 20 seconds, final dehydrate 4 ~ 6 minutes, discharge. Catharsis water pump presses force ≥3.0kg/cm2. ≤13% of portion of discharge machine wet syrup. Thick ≤5mm of candy of centrifuge net wall. Standard of catharsis water quality is ≤10us/cm of endotoxin ≤0.2eu, electrical conductivity. After the lotion that depart gives and mother liquor mix, use at completely before the burden of line working procedure.

(14) dry 3 class pneumatic drying, 2 class sirocco one class air cooling. Temperature is 108 ~ respectively 15 ℃ of 40 ℃ of 115 ℃ , 30 ~ , 5 ~ . Equipment of the 3rd class chooses rolling-type desiccator. Use method of negative pressure pneumatic drying.

(15) pack 80 ~ 100 eye vibrating separator crosses candy pink, robot is packed, every bags of 25 Kg.
