  • Pet Food Production Line - China

    price: 20.00 Dollar US$

    Pet food production line is assigned to pet food with innovative shapes, unique taste and color, and to scientific nutrition proportion and easy to digest and other features to adapt to the constantly evolving pet food market.

    Taste of varied shapes and meet the needs of all kinds of pet food.

    Pet food production line by mixing powder, double screw extruder, air machine, drying and seasoning line composition.

    Pet Food and Aquatic Fish Feed Production Line

    The production line has reasonable equipment design, high degree of automation, precise control of extrusion process parameters and innovative design of temperator, which further improves the curing effect of feed.

    The pet food production line uses high-expansion corn flour grains as the basic raw material, supplemented by bone meal, meat, protein, vitamins, fiber and other nutrients, and cooperates with a screw extruder to produce pet dog food of different shapes through strong extrusion and instantaneous expansion molding.

    Cat food and other food pellets, and also produce aquatic feed floating feed, mackerel feed pellets, goldfish feed pellets, shrimp feed pellets, crab, mud, bullfrog and other feeds and foods.

    The dried flavor coating enhances the taste of the final product, and the final set is automatically packaged.

    The particle size can be from 0.9-15mm to feed fish of different sizes.

    Our pet food production line has high output and high quality products.

    It is the first choice for large and medium-sized feed processing plants, aquaculture farms and pet food industries.

    How is pet food produced?

    Typical raw materials used in pet food processing include grain flour, vegetable protein, minerals and vitamins, and in some cases, meat or fish meal and fresh meat.

    The dry material enters the pre-conditioner + and is steam hydrated.

    The mixer mixes the ingredients and ensures that the steam, moisture and ingredients are properly mixed.

    The pretreatment produces partial gelatinization of the starch and texture of the polymer.

    Then the partially cooked mixture is sent to the double-screw extruder, and the shear, internal temperature, pressure, moisture and residence time are precisely controlled to achieve the best starch gelatinization without losing food quality.

    In different processing stages, liquid or steam can be injected through ports in the extruder barrel.

    An exhaust filler can be used for degassing at this stage.

    Pet food production line production process

    1 - Mix

    The mixing process is a key process in pet food production.

    The basic process is to weigh the raw materials of different weights according to the formula, then pour them into the crusher and smash them, and then temporarily store all the materials in the storage bin.

    Then all the ingredients are ready, put them in the blender and mix them.

    2 - Extrusion

    Extrusion is a high temperature and short time heat treatment process.

    It can not only reduce the degradation of food nutrients, improve the digestibility of protein and starch, but also destroy anti-nutrients and microorganisms.

    Can produce round, triangle, flower shape, bone shape and other shapes of dry pet food through different molds (templates) of the feed extruder.

    In pet food production, fat is usually added to improve the palatability of pet food, which is carried out during the conditioning process.

    In addition, in order to make pet food tablets have different colors, manufacturers usually add pigment water in the extrusion chamber.

    3 - Dry

    The drying part is mainly used to remove moisture from the extruded pet food.

    The extruded material has a soft texture and a water content of 20-30%.

    After drying, the moisture of the finished product is controlled at 8%~10%, which can ensure the storage of the material within a certain period of time.

    4 - Add grease

    Oil is the best source of energy, so 2%-40% of oil can be added to the formula according to the growth needs of the pet.

    We recommend that the fat content in the formula, that is, the total oil content in the extruder should be kept within 12%.

    If the oil content is required to exceed 12%, the hardness of the pellets will be significantly reduced.

    If the extruded material needs to contain more than 12% oil, it is recommended to add additional oil after drying.

    It can be used under normal pressure or vacuum spraying, depending on the amount of oil added.

    The external spray will make the appearance of the pet food flakes more attractive.

    In addition to oil, some powdery attractants are also sprayed to increase the palatability of pet feed.

    5 - Cooling and screening

    The main purpose of the cooling section is to cool the dried material from high temperature to close to room temperature and take away part of the moisture.

    In addition, during this process, unqualified food tablets will be separated from eligible foods.
