鱼料生产主要设备 Fish Feed Production Machine 1. 压力 2. 温度 120-150 ?C Temperature 120-150 ?C 3. 水份 24-28 % Moisture 24-28 % 用膨化机制粒：Pelletization by EXTRUDER - 膨化前的料应满足 : 水份16%, 温度 90 ?C Pre-extruded feed should : moisture 16%, temperature 90 ?C - 水份 24-28 %, 温度 120-150 ?C时熟化效果好 Feed will be good cooked at moisture 24-28 %, temperature 120-150 ?C - 借助于压模和切刀可以控制原料形状与密度。 Be able to control the shape and density by DIE and pellet cut 作用：储存料与保证原料连续送入膨化机。 分料圆桶内的料位不应低于桶高的 1/3 以防止蒸汽倒窜 与湿料粘桶。 Function is staying and keeping feed in order to feed to EXTRUDER constantly. The feed level in circular bin should not less than 1/3 of bin for the purpose of preventing contrary steam and stuck of wet feed. 作用 Function 1. 将料从分料圆桶推送到搅拌罐 Drag feed from Circular Bin to Mixing Cylinder 2. 喂料器电机转速必须能够改变以便可按照操作工的 要求或针对不同品种的料的需要控制送入搅拌罐与 膨化器的料量大小。 Motor of Feeder have to be able to change revolution in order to control the amount of feed drag to Mixer and Extruder as Operator requirement or suitable condition of each kind of feed. 3. 喂料器的种类：最常用的是螺旋式（绞龙） the kind of Feeder, mostly use Screw Feeder 作用 ：使料均匀地搅拌与混合，添加蒸汽提高水份与温度。 它是料熟化的一个初期过程，料的水份大约为 16- 20 %,熟化时间 2 – 4 分钟, 温度 90 ?C 熟化时间 2 – 4 分钟, 温度 90 ?C Function : mixing and blending homogeniously and adding steam for moisture and temperature increase. This is a preliminary process for cooking. Feed moisture is approximately 16 – 20 %, spend 2 – 4 minutes, temperature 90 ?C 搅拌罐有二种型式：MIXING CYLINDER has 2 types 1. 压力熟化器 PRESSURE COOKER 2. 调质器 CONDITIONER 2.1 单轴调质器 SINGLE SHAFT CONDITIONER 2.2 差径调质器 DIFFERENTIAL DIAMETER CONDITIONER 1.单轴调质器桨叶调整 : Mixing paddle setting : SINGLE SHAFT CONDITIONER 2.差径调质器桨叶调整 : Mixing paddle setting : DIFFERENTIAL DIAMETER CONDITIONER 差速调质器中桨叶调整 M
