Operation points
1 The original algae (Cauliflower) should be rinsed once, and the environmental pollution should be spread on the beach. Fresh water should be sprayed 2-3 times a day with fresh water, and the surface is yellowish-white for about 1 week. The algae was flipped and placed in water for 2-3 times a day until all the red chlorophyll was removed.
2 Place the algae on the electric grind to grind all the gravel, shells, and limestone on the algae, inject it into the basin and wash it several times, remove the cement on the floor, and then dry it to pure raw materials.
3 Production of finished products In general, natural winter conditions are used. During the middle of December to the beginning of February, it is the time for the production of frozen powder. The optimum temperature is between -5 and -5 °C. Use an open-type direct-fired heating boiler or a closed-type steam pressure cooker. The ratio of the weight of the raw material to the water is 1:33. The water is injected into the pan and heated to boiling. The material is then poured into the pan and is added after the reboiling. Sulfuric acid and sodium thiosulfate were stirred well, and 180-240 milliliters of sulfuric acid per 100 kilograms of raw algae was added, and the raw materials were dissolved and degummed to form a porridge-like shape. The heating was stopped, the pot was covered, and the pot was continued for another 40 minutes so that the remaining residue after the dissolution was settled. , Filtering starts after 2 hours.
4 using plate and frame filter press or filter bag hot extrusion filter, the general frozen powder should be filtered at 70 °C, each filter 1 filter bag washed with hot water 1 times, the filter residue for the second time cooking The ratio of water is 1:10, and it is boiled for about 30 minutes without adding sulfuric acid and sodium thiosulfate.
5 The filtered pure powdered soup is poured into a small wooden trough, the foam is removed, and after a few hours of cooling, it is solidified into jelly.
6 The frozen powder soup can be cut after it has completely condensed into a flexible colloid. Cut the square bar with a powder knife, transport it to the sun drying area, and put it into the powder breaker. Push it out to make it thin and dry it. It can also be sliced ​​and short.
7Using the freezing in the winter at night, the moisture in the glue will form a frozen block, and the sunrise will melt and queuing moisture to discharge impurities such as salt and pigment in the gel. It usually dries and melts. After 2 weeks, it is freeze-dried.
Frozen powder, also known as agar, agar. It can be used as a laxative in the treatment of constipation in medicine, and it can also be used as a pharmaceutical paper and bacterial culture medium. It can also be used as a lubricant for paints, pastes, printing offset plates, production models, and tungsten filaments in industry. It is also widely used in the food industry.
