Our country is a big agricultural country. The straw resources are very rich and the output is considerable, but they cannot be used rationally. Only 15% to 20% are used for livestock feed. More than 80% of the straw resources may be burned as energy. Or destroy the fields, resulting in a huge waste of resources and environmental pollution. At the same time, the rapid development of animal husbandry has exacerbated the conflict between humans and animals competing for food.


As the proportion of cattle and sheep kept increasing year by year and the need for large-scale and intensive breeding, as well as to ensure the stable development of animal husbandry, to resist the huge losses caused by natural disasters such as white disasters, locust plagues and droughts, forage and straw The demand for straw feed products in the international market is also very strong. Japan, South Korea and Southeast Asia all need a large amount of straw forage feed. In the past, most of the grass products were imported from major forage grass producing countries such as the United States, Canada and Australia. Due to long distances, high freight, and high labor costs in these countries, the cost of grass products is high. With its geographical advantages and cheap labor in the Asian market, China is expected to occupy more shares in the Asian grass products market.

Among them, 1,000 square meters of workshop workshop (400 square meters of straw crushing workshop, 200 square meters of high-pressure and high-temperature sterilization workshop, 200 square meters of gelatinization module backlog molding-particle-puffing-drying workshop, 100 square meters of automatic packaging workshop, 100 square meters of inspection room Square meters), fermentation tank 200 square meters, warehouse 3400 square meters, drying area 4000 square meters, office dormitory and auxiliary 2360 square meters.

2. Equipment

Introduced 10 sets of SZLH feed pellet machine equipment from Richi Machinery, purchased 4 transport vehicles and 3 12mX4m floor scales.

III. Project Implementation Progress

Due to the mature production technology of this project, as long as the construction funds are in place, the project construction period is one year according to the relevant standards of the domestic construction industry. The specific implementation progress is as follows:

1. From October 2011 to March 2012, fund raising for project design, geological prospecting, and production equipment test score construction.

2. The civil engineering started in April 2012 and completed in September.

3. Enterprise management, production quota and technical training in May 2012.

4. In October 2012, the equipment was installed and debugged.

5. Mass production will begin in November 2012.

6. The production reached the standard in June 2013.

IV. Technical Requirements for the Production and Processing of Feed Pellets

Pellet processing is a deep processing process in feed processing. The technical requirements are relatively high, from the matching of conditioners, pelletizers and extruders to the design of coolers, pellet stability after pelleting, and liquid addition systems. These requirements are for obtaining high-quality pellet feed.

1. Conditioning

Conditioning is a process of hydrothermal treatment before pelleting to soften the powder. In traditional feed mills, conditioning before pelleting is a more difficult link, and any single conditioning time cannot be the best conditioning time for all feeds, so the conditioning time needs to be changed. It has long been known that the conditioning residence time has an effect on the conditioning and pelleting quality. In recent years, Europe has made several innovations in this regard, including conditioner angle, blade angle adjustment and steam or powder plugging.

2. Feed Pellet Machine

Pellet feed has many advantages. Through the combined effect of steam heat, mechanical friction energy and pressure, it can achieve many functions of sterilization and increase feed digestibility. However, excessive heat processing will cause the actual effect of heat-sensitive nutrients and reduce the feed Therefore, effective processing is the latest development trend.

3. Puffing

At present, the main equipment for producing extruded feed is screw extruder, which can be divided into dry extruder and wet extruder. Most of the current extrusion equipment is wet and dry.

4. Cool Down

Almost all new feed mills use countercurrent coolers.

5. Liquid Addition After Granulation

As more and more thermal processing equipment is used in feed factory equipment, such as extruders, extruders or other high-temperature short-time processing equipment, the feed is strongly affected by temperature, moisture and pressure during pelleting, extrusion and expansion. , Which will destroy most of the efficacy of vitamins, enzyme preparations, probiotics and other additives. The post-adding technology is a new technology to solve this problem, that is, adding heat-sensitive nutrients after the thermal processing process.

V. Processing Technology of Straw Feed

1. Required equipment, tools, raw materials

Ordinary pulverizer, optional SFSP series, 3-20 tons per hour and other models, power 30-160 kilowatts. Granulator, SZLH type can be selected, power 22-315KW, output 1-40 tons/hour.

2. Pick straw

Common crops such as wheat, corn, stalks or vines, peanuts, mung beans, sweet potatoes, etc., pods, corn cobs, peanut shells, locust leaves and elm leaves can all be used. In the harvest season, select clean straws, remove the roots, spread and dry them, remove dust and debris, stack them for storage, and take measures to prevent moldy and deterioration.

3. Preparation of middle song

There are many kinds of starter, and you can prepare starter Zhongqu by yourself. Take 15 kg of wheat bran, 35 kg of bran, 0.5 kg of rice wine koji, 0.5 kg of sauce koji, 0.5 kg of vinegar koji, and 50 kg of cold boiled water. After mixing the above-mentioned powders, add water gradually and continuously Mix and knead with your hands. When you hold it into a ball, do not add water when it is not scattered or dripping. Then put it into a ball with a diameter of 10 cm and place it on a clean indoor corner, and cover with weeds. When the temperature rises to 42°C, remove the weeds on it. It usually takes 3-4 days to complete. After drying Ready to use. The finished product is in the shape of a hard ball, yellow-black, no odor, and valid for about one year. It can be used after being crushed with a grinder.

4. Production of semi-finished products

Process cutting → crushing → soaking → cooking → irradiation → puffing → thermal spray → granulation → semi-finished products

VI. Investment Budget and Benefit Analysis

(1) Production cost estimation

Take 20 tons of pellet feed in a shift as an example, the specific analysis is as follows

1. Raw materials: corn stalks, soybean stalks, straw, etc., 0.04 RMB/kg×2000 kg=80 RMB/ton

2. Electricity fee: 1 RMB/kWh. Total power 7.5KW

7.5 degrees / hour × 1 RMB / degree × 5 hours ÷ 20 tons = 0.375 RMB

3. Biological bacteria and dressing: 17.5 RMB/ton

4. Packing fee: 20 pieces/ton×2 RMB/piece=40 RMB/ton

5. Fuel cost: 0.4 RMB/ton (consumption) × 20 tons = 8 RMB

6. Water fee: 0.5 RMB/ton (consumption) × 5 tons = 2.5 RMB

7. Management fees, expenses, equipment depreciation fees, etc.: 20 RMB/ton

8. Labor cost: monthly salary of workers is 1500 RMB, 1500×10 people ÷ 30 days ÷ 20 tons = 25 (RMB/ton)

9. Depreciation of fixed assets:

Building depreciation (30 years)=967.20×5%=48.36

Equipment depreciation: (15 years)=1239.4×8%=99.15

Total cost: 80+0.375+62+20+10=363.39 RMB/ton

363.39 RMB / ton × 10,000 tons = 36.339 million RMB

(2) Estimated sales revenue

Ensure that the product output is 10,000 tons, sold at 4,000 RMB per ton, and the annual sales revenue totals 40 million RMB

(3) Taxes and surcharges

According to national regulations, this project is a tax-exempt enterprise.

Urban construction and maintenance costs: 4000×5%=2 million RMB

Education surcharge: 4000×3%=1.2 million RMB

(4) Project profit calculation

1. Sales profit = sales revenue-sales expenses = 4000-3633.9 = 3.661 million RMB

2. Sales profit rate=sales profit/sales revenue×100%=366.1/4000×100%=9.15%

3. Profit rate of cost of sales=Sales profit/Total cost×100%=366.1/3633.9×100%=10.1%

(5) Analysis of financial benefits

1. Investment profit rate=sales income/total project investment×100%=4000/2866.6×100%=139.54%

2. Investment payback period = investment amount / estimated annual profit + annual depreciation = 2866.6/366.1+147.51 = 5.58 (years)
