First, the sun monotonous method: the sun is the most convenient and easy way, the method is: the timely harvest of mushrooms in sunny sun valley or cement ground. When the sun first, the mushroom is covered upwards, and the mushroom shank is turned downwards. One by one, the sun is dried until it is half dry, the mushroom shank is upward, and the mushroom is covered downward, until 90% dry is suitable. In case of rain, add firepower to dry. Second, baking monotonous method: mushrooms should be packed in a small basket, do not put too much, so as not to squeeze, and should be baked on the same day. The usual practice is: The harvested mushrooms are spread on a baking screen and sent to the drying room. The temperature should not exceed 40°C at the beginning, and it should be increased by 5°C every 3-4 hours thereafter. The maximum temperature should not exceed 65°C. Drying room should have exhaust facilities, while the side of the exhaust side of the exhaust, otherwise the mushroom folds will become black and affect the quality. After 80% dry, take out the airing for several hours and re-brake for 3-4 hours until the water content reaches 13% or less. The shiitake mushrooms that are baked will have a monotonous, good color and a strong flavor. The shiitake mushrooms after dried should be promptly graded and quickly sealed after classification, and stored in a monotonous and cool place.
Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
I. Poly Aluminium Chloride Properties
Product Name:
Polyaluminium Chloride (Poly Aluminum Chloirde, Polyaluminum Chloride, Poly Aluminium Chloirde, Aluminum Polychride, PAC )
CAS#:
1327-41-9
Appearance:
White and yellow powder
Description:
Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.
Different grades of Polyaluminum Chlorides (PAC). The highly charged Al in the products is optimized for best performance for the different basicities of PAC. The low to medium basicity products are effective coagulants for treatment of both drinking water and waste water. And the medium to high basicity products are excellent for all ranges of wastewater treatment.
III. Poly Aluminium Chloride Application:
1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.
2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.
3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.
4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.
5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.

1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants.
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants.
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility.
4. It is slightly corrosive and easy for operation.
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.
