In recent years, the requirements for the technical parameters of wort filtration are getting higher and higher, and it is necessary to be able to obtain as much clarified wort as possible to improve the production efficiency and yield under the premise of ensuring that the filtered wort reaches the quality requirements required for production. Therefore, higher requirements are also imposed on the wort filtration equipment. Most brewery's wort filtration is done through a filter tank. However, in recent years, with the continuous changes in beer technology and raw and auxiliary materials, the wort filter press has become increasingly popular. With the advent of many new types of wort filter presses, they have overcome many of the drawbacks of previous wort filter presses, which can meet the current beer production in terms of wort yield, production efficiency, Automation and production costs. Claim. As a result, many modern large beer groups have chosen to use a wort filter for wort filtration. 3D Laser Tracker With Double Laser,Manufacturing Laser Tracker,3D Laser Tracker,Double Laser Tracker Automated Precision Inc. , https://www.apiasean.com
Since the 40s and 50s, foreign countries have been developing and using wort filter presses. Due to the limitations of the time, most of the filter plates are made of cast iron. The filter cloths are made of ordinary cotton cloth. The wort filtration turbidity is not ideal, labor intensity is large, and filtration Each batch of cloth must be disassembled and cleaned, and the production environment is bad. This wort filter press was quickly eliminated due to turbid wort, difficult to clean filter cloth, and high labor intensity.
In the 1990s, the international use of polypropylene raw materials to produce filter plates and filter cloth, this material has the characteristics of good thermal insulation performance, light weight, can meet food production requirements, filter cloth can be cleaned once a week, labor intensity is small, etc. The wort filter press has entered a period of rapid development, and many brewers have adopted it in the reconstruction and expansion.
Designed and produced by Harbin Hande Light Industry Medical Equipment Co., Ltd., the HDGL-1800 type wort filter press was put into use in Liaoning Fushun Tianhu Beer Co., Ltd. in 1999, and passed the ministerial appraisal in September of the same year. After five years of use, the machine has stable performance and good running condition, and has been determined by the manufacturer. At present, due to its reasonable price and price ratio, this series of equipment has been applied in several beer companies across the country, such as Dalian Daxue Beer Co., Ltd., Henan Yueshan Beer Co., Ltd., Gansu Agricultural Beer Co., Ltd., Inner Mongolia Jinchuan Health Beer Co., Ltd., Henan More than ten beer companies, such as Wei Xue Beer Co., Ltd. and Harbin Beer (Helen) Co., Ltd., have been put into use.
How can domestically produced wort filter press be applied and recognized in several beer companies in such a short period of time, and some beer companies use the second and third sets in the expansion, from the perspective of beer companies Look, the choice of wort filter press is mainly considered from the following aspects:
First, improve production efficiency can meet 12 batches of saccharification every day, and more than 13-14 times.
Filtration can be carried out under high wort viscosity, and filtration is not affected by the quality of the raw materials.
It is suitable for the brewery to produce high-concentration wort. It can increase the yield by high-concentration dilution. The concentration of wort can reach 30°P, and the concentration of wort can reach above 15°P.
It is especially suitable for the expansion of the original saccharification workshop. It only needs to change the original old-fashioned filter tank into a saccharification pot to double the saccharification output, saving more than 50% of the funds directly invested in a saccharification system. The amount of wort that can be produced far exceeds the wort filter tank.
Second, reduce production costs
1. Higher saccharification chamber utilization. The raw material can be hammer mill, fine pulverization can increase the specific surface area of ​​the raw material in the saccharification reaction, increase the saccharification yield, the actual leaching rate of the saccharification chamber is basically equal to the leaching rate of the laboratory, and the high leaching rate and raw material utilization can reduce the cost. .
2. Can adapt to different accessories. Due to the rising prices of raw materials, many companies have begun to increase the proportion of excipients, and consider adding ingredients such as starch and syrup. Increasing the proportion of excipients has no significant effect on the speed and time of filtration.
3. It is possible to produce wort using raw materials without husks, and saccharification can be carried out using high proportions of auxiliary materials. At present, domestic enterprises have begun to use barley malt instead of wheat buds and accessories.
4. The feeding amount is flexible, and the movable filter blind plate can be set to adapt to different feeding amounts. It is especially suitable for beer enterprises in some areas with obvious peak seasons.
Third, improve the quality of the product throughout the filtration, washing process, are in a closed state, reducing the oxidation process in the wort filtration process.
The wort has low turbidity and a relatively low solid content, and the solid content per liter of filtered wort can be less than 5 ml; using a low temperature, short time washing technology, the filter plate made of reinforced polypropylene material has good Insulation performance, can be washed at a lower temperature; there is a lower consumption of washing water (2.5 HL water per 1000 g of malt, while traditional filter tank requires about 4 HL water), so it can shorten the washing time and prevent Leaching of harmful ingredients in wheat husks.
The continuous washing method is alternately carried out from the plate to the plate. The washing water passes through the filter cloth from one side of the filter plate into the bad layer, then passes through the bad layer and the filter cloth, and enters the other side filter plate which is not washed with water. Alternate washing methods avoid uneven washing and short-circuiting.
Fourth, improve the labor environment and the production environment fully automatic operation, the degree of equipment automation reached the international level, reducing labor intensity. The processes of feeding, refluxing, filtering, washing the waste, unloading the waste, and discharging the waste are all completed automatically.
Easy to maintain, CIP cleaning only needs to be done once in batches of 60-80.
There are dry wheat grains, the dry matter content can reach about 27%, which is 70% less than the traditional filter tank, the transportation cost is greatly reduced, and it is not easy to pollute the environment such as road surface, especially for drying wheat grains. Reduce the cost of drying the grain and carrying out wastewater treatment.
In summary, it is not difficult to see that under the situation of resource shortage and lack of energy, due to the technical advantages of the wort filter press, it will play a greater role in improving the production efficiency and energy saving of beer enterprises. Gradually accepted by more and more companies.
