Modern animal dry glue is also easy to be made into glue when it is used. Dry glue can be directly dissolved in mechanically stirred hot water at a temperature of 65~ 77C, and then gradually cooled to 60~63 C. This is the best temperature range for the effective operation of animal glue. The preparation time of each batch of glue solution is usually 30 ~ 60 minutes. On the other hand, the preparation method of the glue solution is as follows: firstly, it is soaked in cold water until it swells (it takes 30-45 minutes), and then it is transferred to a jacketed melting tank equipped with a stirrer to melt and stir into a solution. This method is suitable for small batch and multiple batch production. In order to get the best results, dry glue should always be measured by quality and quantity, not by volume (which may cause great differences and mistakes). The required amount of water should also be weighed first, and then water can be added according to the marking scale made by the finished batch. For mixing tanks, galvanized iron and stainless steel, iron cans and copper are preferred, and long-term heating may cause the glue solution to fade. Jacket hydropower heating method can be used for smaller and larger mixing tanks. The mixing tank shall be heated by low pressure steam.
