The advantages and disadvantages of electric heating and steam heating are due to the fact that most of the commercial brewing equipment requires step-by-step saccharification, so that the temperature rise is required in the saccharification process, and the heating mode and the design requirements are relatively high. The electric heating has the advantages that the price is low, the defect is that the temperature of the large equipment is relatively slow and the local level is too high, the heating area is constant, the heating area is large, and the heating process of the mash liquid can be ensured to be more uniform, The degradation of the starch and the protein in the malt is ideal; the phenomenon of the electric heating paste pot does not occur; the paste can influence the taste of the wine; and the washing pot is cleaned.
In the case of 500 liters as an example, what is the electricity consumption of electric heating? 30Kw (normal is six sets of 5Kw heating pipes)2. What is the electricity consumption of the steam heating electric boiler? 36 Kw 3, what is the electricity consumption of the liquefied gas boiler for steam heating? 0.75 Kw (water supply pump)4,3-4 Kg/ h of liquefied petroleum gas for steam heating,4-5 Kg/ h of natural gas and 9-10 Kg/ h of gas. What is the cost of using a better steam boiler than that of electric heating? During normal wort preparation, the heating time is 3.5 -4 hours, the electric heating power is 105-120 degrees, the electricity consumption of the electric boiler is 126-144 degrees, the electricity consumption of the liquefied gas or natural gas boiler is less than 3 degrees, and the natural gas is used for 14-20Kg. according to the commercial power consumption of 1.1 yuan per degree, the peak price of the natural gas is 4 yuan/ Kg, the electric heating power consumption cost is 115-130 yuan, the average heating cost per liter of the wine is 0.23-0.26 yuan, the electricity consumption cost of the electric boiler is 138-158 yuan, the average heating cost per liter of the wine is 0.28-0.32 yuan, and the electricity consumption of the liquefied gas or natural gas boiler is less than 3.5 yuan, The liquefied gas is used for 56-80 yuan, the total cost is 60-83 yuan, the heating cost of each liter of wine is 0.12-0.17 yuan, the electric heating tube is directly heated, the equipment does not have a heating capacity of 50Kg, the power is 36Kw electric boiler, the softened water is matched with the softened water, the cost is more than 10000 yuan, the evaporation capacity is 50Kg of the liquefied gas boiler, the softened water is provided, the cost is about 15000 yuan.
