The advantages and disadvantages of the milling method

The advantages and disadvantages of the milling method

The last time we talked about the four ways to smash, here we learn together the advantages and disadvantages of these methods.

Refer to the following list:

Milling method	advantages	disadvantages
Dry crushed	1.Low requirements on the equipment, easy to operate	1.Crushing chamber and saccharification room to be separated, combined with malt storage silo and powder storage, higher fixed investment
	2.Low energy consumption and centralized power supply	2.Crust easy to crush, crushing degree affected by the moisture of raw materials
	3.Endosperm drying, crushing effect is good	3. Filter tank unit area load is small, only 190kg / ㎡
	4.Powder dry, can be stored for a long time	4.Large dust, the risk of dust explosion
	5.The skin and the contents can be separated and separately fed
Wet grinding	1.Crushing operation can be carried out in the saccharification chamber, fixed investment is low	1.Larger amount of input material, often 2-3 sets of wet powder machine at the same time, concentrated electricity load, high power consumption
	2.Mashing and crushing are carried out continuously	2.Mashing and crushing are carried out continuously
	3.The skin is more complete, wort filtration effect is good	3. Because soaking a longer time, tannin leaching more
	4.Filter tank per unit area load, up to 250-350kg / ㎡	4.After each use need to brush, poor sanitary conditions easily lead to pollution
	5.No dust pollution
Resurgence moisturizing method	1.Similar to dry crushing	1Crushing chamber and saccharification room to be separated, combined with malt storage silo and powder storage, higher fixed investment
	2.A more complete hull, saccharification utilization and wort filtration performance have increased	2.Filter tank unit area load is small, only 220kg / ㎡
		3.High energy consumption, power consumption is 2.5-3 times the dry crushed
		4.There are still dust
Impregnation humidification method	1. Crushing operation can be carried out in the saccharification chamber, fixed investment is low	1. On the crusher production capacity requirements, higher concentration of electricity load
	2. Impregnation time is short and fixed, saccharification and crushing simultaneously	2. Equipment and piping need to use stainless steel, large investment
	3.400-550mm Filtration tank per unit area of the larger load, up to 250-350kg / ㎡. Malty layer height of up to 400-550mm	3. Equipment health requirements higher, or easily contaminated bacteria
	4.Crust less broken, less leaching tannin, wort transparency, saccharification yield high
	5.Put an end to the dust pollution
