Twin-screw puffed food equipment is a kind of puffed food equipment suitable for China's national conditions, which is developed by using twin-screw extrusion technology and combining with our company's rich experience in puffed food technology research for many years. The equipment is characterized in that it can be processed with corn, rice, millet, black rice, mung bean, buckwheat, oat and other non-five-ancient grains as raw materials according to market demand, and has various flavors through forced extrusion, puffing, molding drying, oil injection, seasoning and corresponding auxiliary processes The production line is reasonable in design, high in automation, high in output and good in technology, and the main engine adopts frequency conversion speed regulation system, which is powerful. This production line belongs to the domestic high level, and its development and production fill the gap of single output of domestic small diameter screw extrusion equipment.
Twin-screw puffing equipment can produce puffed snack foods, such as brown rice rolls, rice fruits, and roasted wheat, pet granular foods, fried snack foods, nutritious rice flour foods, cornflakes porridge foods, nutritious rice, golden rice fortified rice foods, protein foods, and modified starch. It is characterized by simple process, low cost, high utilization rate of raw materials and high degree of automation, and is widely used in food, feed, medicine, chemical industry and other industries.
在技术服务的过程中，经常遇到一些企业在生产狗粮、猫粮时，膨化颗粒不稳定，时而膨化过大、时而膨化过小、甚至是不膨化，导致产品质量其不稳定，这是为什么呢?
影响膨化容重的因素有哪些?
1、 原料配方营养成分比例;
2、 营养性原料的质量;
3、 调质蒸汽温度、水分、压力(适于湿法膨化工艺);
4、 喂料速度;
5、 主螺杆转速;
In the process of technical service, some enterprises often encounter unstable expanded particles in the production of dog food and cat food, sometimes too large, sometimes too small, or even not expanded, resulting in extremely unstable product quality. Why?
What are the factors affecting the bulk density of expansion?
1. Proportion of nutrients in raw material formula;
2. Quality of nutritional raw materials;
3. Temperature, moisture and pressure of quenched and tempered steam (suitable for wet expansion process);
4. Feeding speed;
5. Main screw speed;
小型狗粮设备生产线一般包括7个设备
1.混合机（混合多种物料原料）
2. 螺旋上料机（输送物料到膨化机)
3.双螺杆狗粮膨化机（膨化原料成颗粒状，更换磨具可以变成不同形状）
4.风送机（风送物料到烘干机）
5.烘干机（烘干狗粮到合格的水分范围，保质期长）
6.喷油调味系统（可选用八角调味机，或者滚筒调味机）
宠物饲料调味过程：狗粮的各种味道和不同能量需求的微量元素在调味过程中添加到颗粒表面。一般狗粮都需要通过调味设备实现喷油、喷浆、喷粉的功能。根据可以达到调味功能的设备有八角调味机、滚筒式连续调味机、批次称重式喷油调味机。中小型宠物食品生产线使用批次混合调味机好，调味均匀，添加量。满足不同品种产调味需求，自动化运行，滚筒式调味机也具有连续自动化生产的优势，但是混合时间和均匀性要低于批次式混合调味机。
干法生产工艺：原料粉碎-混合-挤压膨化-烘干-喷油调味-冷却-包装
湿法生产工艺：原料粉碎-混合-调制-挤压膨化-烘干-喷油调味-冷却-包装
设备配置一:拌粉机-螺旋输送机-调制器-双螺杆膨化机-风送机-烘干机-双滚筒调味机-冷却机
Pet feed seasoning process: various flavors of dog food and trace elements with different energy requirements are added to the particle surface during the seasoning process. General dog food needs to realize the functions of oil injection, slurry spraying and powder spraying through seasoning equipment. According to the equipment that can achieve the seasoning function, there are octagonal seasoning machine, drum continuous seasoning machine and batch weighing oil injection seasoning machine. Small and medium-sized pet food production lines use batch mixing seasoning machines with good seasoning uniformity and addition amount. The drum seasoning machine also has the advantages of continuous automatic production, but the mixing time and uniformity are lower than those of batch seasoning machine.
Dry production process: raw material crushing - mixing - extrusion - drying - oil injection seasoning - cooling - packaging
Wet production process: raw material crushing - mixing - modulation - extrusion - drying - oil injection seasoning - cooling - packaging
Equipment configuration 1: powder mixer - screw conveyor - modulator - Twin Screw Extruder - air blower - dryer - double drum seasoning machine - cooler
开个狗粮加工厂挣钱吗?很多人对这个问题比较关心，现在养宠物的越来越多，以前是喂剩菜剩饭，现在喂食方便，营养全面的宠物食品膨化粮广受喜爱，人们的生活水平提高，宠物食品占据一部分开销，宠物食品厂应运而生，有些人开始想投资狗粮加工厂，开个宠物食品厂可以从中小型做起，投资少，回本快，利润高，一般一吨狗粮500-10000元利润不等，自己加工可以抓质量。
Do you make money by opening a dog food processing factory? Many people are more concerned about this problem. Now more and more people have pets. In the past, they used to feed leftovers. Now, pet food puffed food with convenient feeding and comprehensive nutrition is widely loved. People's living standards are improved. Pet food accounts for part of the expenses. Pet food factories should be born. Some people begin to want to invest in dog food processing factories, Opening a pet food factory can start from small and medium-sized ones, with less investment, fast cost recovery and high profit. Generally, the profit of 500-10000 yuan per ton of dog food varies. Self processing can pay attention to quality.
