Project background: a small-scale craft brewery, with a county as the center, radiating the supply output of 2-3 counties around it.
Planning Principles
1. When selecting equipment, it should meet the requirements of the production process, while being safe and reliable. Try to use complete sets of equipment and general equipment to help improve the degree of mechanization, facilitate production, and save investment
2. This design minimizes or does not occupy arable land, and the selection process is minimized to avoid pollutant discharge. Minimize the amount of waste treatment, while paying attention to energy saving and making full use of waste heat.
3. According to the actual situation, reasonably determine the product variety of the factory and arrange the product plan of the factory according to the needs of the country, taking into account economic and social benefits, and returning the largest economic benefits with the smallest investment
Design Features:
1. This design is based on reality, pays attention to efficiency, and strives to achieve greater economic benefits with less manpower, material resources and financial resources in each bad section of production. This is the guiding ideology of this design, and it is also the most important feature of this design
2. This design determines the product from the sales in the domestic market, so that the product has a strong competitiveness in the market.
3. The site of this design is in the outskirts of the city. In terms of labor, power, water supply, drainage engineering and living facilities, the original facilities of the city can be used to reduce investment
4. This design starts from saving land and makes full use of plant equipment to arrange products. For those with different types, production equipment and production conditions are very the same, and even the same plant and equipment are used to produce different products. This is for plant land and equipment investment. Very advantageous
5. This design is that the product hygiene meets the food hygiene regulations and comply with the relevant provisions
Fourth, the principle of site selection
1. The plant meets the requirements of environmental review
2. There must be a reliable water source, which should be as close to the water as possible under the conditions of meeting the water quality, quantity and temperature of the brewery's production water.
To shorten the laying of pipelines and power cables, such as mountain spring water, underground water, reservoir water, tap water or river water, etc.
Use one water source alone, or use two or three water sources separately for production
3. Consider the location of the factory site according to different transportation methods. If raw materials and finished products are mainly transported by water, they should be as close to the river as possible
4. The plant site should be as close as possible to some existing heat and power sources. To fully obtain the conditions for corporate collaboration
5. The factory site should be as close as possible to the town or beer sales area to reduce transportation costs
Five, general graphic design principles
(1) Meet the production process requirements.
(2) The layout is compact and reasonable, saving land, and leaving room for long-term development.
The production workshop is the center of the factory, and other departments are developed around it. They should be a coordinated whole. therefore,
The relationship with other departments and the development prospects of the factory must be considered to meet the overall design requirements
(3) Must meet the food factory sanitation requirements and food sanitation requirements.
(4) Optimize the building spacing and design according to relevant plans.
(5) Adapt to transportation requirements.
Six, wine product selection
When the product plan is drawn up, list several product plans for comparison and discussion. Analyze and determine a more reasonable product plan as a public
An important basis for beneficial design
Determine product variety; 12-degree pale beer
Product output: 2000 tons per year
Product production period: November/December is the off-season, other months are the peak season, off-season saccharification 2-3 batches
High season saccharification 4-6 batches
Seven, beer process
8. Equipment selection and calculation
Suppose saccharification 4 times a day during peak production season, 2 saccharification during off-season, 150 days in off-season and 150 days in peak season, total saccharification per year
The number of times is 900. 2 pots of wort are packed in a cone-shaped fermentation tank. It can be calculated from this:
The saccharification quota is 2000 tons/900=2.2 tons of wort
During the peak season, it produces 8.88 tons about 9 tons a day
4.44 tons per day in the off-season, about 4.5 tons
Determine the saccharification system selection: the effective volume of the saccharification system is 2.5 tons, and the effective 2.5 tons of fermentation tanks are used
According to the fermentation process; the number of fermentation tanks is determined:
N-the number of fermentation tanks required
T-fermentation cycle
N-saccharification times per day
A-The number of batches of wort that each fermenter can hold
3- Turnover quantity
The fermentation period is calculated as 15 days
Available: The number of fermentation tanks is 27 fermentation tanks with a volume of 2.5 tons.
Since there are at least 2 batches of saccharification per day, at least 5 tons of fermentation tanks can be used to save the number of containers, save land and reduce investment budget.
18 5 ton fermentation tanks and 2 5 ton sake tanks are used for later supporting filling.

Before the malt mash is pumped into the filter tank, the filter spreading water has just not passed the sieve plate. After spreading the water, immediately pump the malt mash into the filter tank, and control the rotation speed of the tiller at 5~6rpm/min. When the mash is pumped in half, the mash will flow back and pump the mash, and the mash will end.
Turn off and stir. After the wort returns to a clear level, raise the tiller to a high point, adjust the wort frequency conversion frequency and the speed of the tiller, and start filtering the wort. When the wort is about 1cm away from the fermented noodles, start to wash the fermented rice.

At the same time, the expansion liquid and cold wort can be mixed into the fermentation tank through the wort oxygenation device. That is to ensure the full mixing of the expansion liquid, cold wort and oxygen, and realize that any fermentation tank can enter the expansion liquid, thereby ensuring the flexibility of production. At the same time, due to the use of a double-seat valve, the yeast expansion pipeline sterilization and wort cooling can be performed simultaneously, that is, the repeated sterilization and dead ends of the pipeline are reduced, and the reliability of the operation is improved.
7) Expansion culture: After the seed solution is cultivated in the Karscher tank for 36 hours, it is transferred to the first-level expansion tank for cultivation, the expansion ratio is 1:10, the culture temperature is 15 ℃, and after 55 hours of cultivation, it is transferred to the second-level expansion, and then Return pressure to the first level to expand the cultivation and protect the seeds.

Pneumatic butterfly valve is installed, and manual butterfly valve is installed at the outlet. Able to realize automatic temperature control. After the wort is full, it is naturally heated to 10°C and fermented at the specified temperature. When the sugar content drops to 5.0oBx, the temperature is raised to 12°C to keep it warm. When the sugar content drops to the sealing sugar content, the can is sealed for diacetyl reduction and the can is sealed The yeast was recovered at 96h. When the diacetyl test was lower than 0.08ppm, the temperature was lowered to 0℃ for storage. 10h before the wine is filtered, add 600ppm silica gel to control the wine temperature. At 1℃, keep the contact time between silica gel and wine not less than 4h to ensure that the sake is clear in the later stage.
10) Wine filtering: add silica gel and wait for the wine to be filtered, then enter the sake tank after passing through the candle filter and membrane trap. After the sake tank is allowed to stand for 4-6 hours, it can be packaged and filled.
11) Instant sterilization: After the heat exchange between steam and water, use hot water to heat the sake at 2~4℃ to 72℃, and keep it in the buffer tube for 30S. After the sterilization, the beer and the sake exchange heat. After the heat exchange, the beer and the refrigerant After the heat exchange is cooled to 2-4°C, it enters the buffer tank to stabilize, and then enters the aseptic filling machine, ready for filling. After the sake heat exchange, it exchanges heat with hot water to reach 72℃, keep it for 30S, and repeat the above operation.
