According to Latin American media reports, Brazil’s National Petroleum Administration announced recently that as of the end of last year, Brazil’s proved oil reserves reached 12.623 billion barrels, 3.6% more than at the end of 2006, making the country’s oil reserves second only to Venezuela in South America. second. In addition, Brazil’s proven natural gas reserves as of the end of last year increased 4.9% from the end of 2006 to 364.9 billion cubic meters, ranking second only to Venezuela, Bolivia, and Argentina.
1. Raw material pulverization: Raw materials are mainly divided into two categories, starch and fat. Starch is mainly various grains. Its pulverization can be achieved by ordinary pulverizers. It only needs to ensure the fineness and clean raw materials during the pulverization process. Hygiene can be. Use a colloid mill to pulverize into separate packs or puree, and the meat only needs to be pulverized into meat puree or powder with a colloid mill, and then added to the grain powder and stirred evenly.

The newly increased proven reserves of oil and natural gas are mainly from the Camps Basin in the waters of Rio de Janeiro, in the southeast of Brazil. The Camps Basin covers an area of ​​more than one hundred square kilometers, and the daily production of oil and gas now accounts for 80% of Brazil’s total output of 2 million barrels.
In December 2007, Petrobras announced the discovery of a huge oil field, Tupi Oilfield, with a predicted reserve of 5 billion to 8 billion barrels in the deep sea area of ​​southeastern Brazil. This is also one of the largest oil fields discovered in the world in the past 30 years. However, the oil field reserves have not been included in Brazil's new proven reserves.
2. Raw material mixing: The mixing equipment has two functions, one is to mix all kinds of raw materials evenly, and the other is to adjust the moisture and humidity. It is generally a vertical rapid mixer: the mixing time is short, the mixing is completed quickly, and the machine is used before the humidity of the raw material changes significantly, which ensures the uniformity and quality of the puffing of the dog food particles. The disadvantage is: the single-cylinder mixing capacity is small, and it needs to be stirred all the time during the production process.
3. Raw material extrusion, puffing and curing molding: The twin-screw extruder extrudes and extrudes under high temperature and high pressure, and produces dog food and cat food particles of different styles and shapes by changing different molds. For different raw material ratios and humidity, it is necessary to adjust the temperature and screw speed of different regions and the feeding speed of the feeder to ensure that the produced dog food particles are of high quality and good appearance.
