膨化机调试注意事项

膨化食品的品牌、种类、口味都很多.很多人都爱吃它,尤其是小朋友.膨化食品机械,可加工日常生活中的大米、玉米、大豆、小麦等.其主要的工作原理就是机械能转变成热能,用机器转动的时候产生的热量将食品挤压熟,经过膨化的食品zui明显的特点就是体积变大.膨化食品机械功能多样使其广泛应用于食品,饲料以及工业等领域,以膨化机为基础,我们在此介绍在食品或者饲料处理过程中其中功能,让我们一起看一下吧!
　　1 调试前的检查与准备工作
1.1 调试前的检查
调试前的检查主要有以下几点：
检查各部位，特别是各段膨化腔的连接螺钉、地脚螺栓、电机座与机架的连接螺栓、膨
化腔与机架的螺栓联接，不得有松动现象
电机接线合处的各段线路检查
 手动使主轴转动，此时膨化腔内不得有任何碰擦声音，如有碰擦声音需要调整，详细方
1.1.1 膨化腔与螺杆间隙的调整
 检查并清理水路、汽路。所有过滤器需清理
 检查旁通导料板转动是否灵活自如
为减少振动以及保证皮带传动的平稳性，电机皮带轮的端面和膨化腔主轴皮带轮端面必须保持在同一平面内。这可通过装在两皮带轮中间的锥形胀套结构来调整皮带轮在轴上的位置，以达到上述要求。传动三角带过松，则易打滑，过紧则对轴的拉力过大，降低三角带的使用寿命。通过调节电机导轨上的张紧螺栓，使三角带的张紧度处于适当装态，即用29kg 的力作用在皮带直边的中点。并使其挠曲偏移量为14mm 时为适当，同时要注意电机轴与主轴平行。各个防护罩是否安装到位检查油箱与轴承座有无漏油的发生，如油位下降需要补充循环冷却轴承油根据指示标牌检查各个电机的正反转，并作相应调整所有电机空机运转，检查有无异常现象
1.1.1 膨化腔与螺杆间隙的调整
【说明】
在每次开机时都必须保证螺杆在运转过程中与膨化腔内壁没有任何碰擦声音。如膨化腔偏位，螺杆在运转过程中与膨化腔摩擦撞击，会大大影响螺杆的使用寿命，甚至直接把螺杆打碎。同时在生产过程中，膨化腔偏心也会使生产不稳定，影响产量。仅在主机空转时膨化腔没有任何碰擦声音才说明调整适合。

1.2 调试前的准备工作
1.2.1 原料的准备

An inspection and preparation prior to commissioning
1.1Checks before commissioning
Checks before commissioning the following main points :
Check all parts , especially the connecting bolts attaching screws paragraphs puffing chamber , bolt, motor seat and rack expansion
Bolt connection of the cavity and the rack, without loosening
Check the motor wiring line segments together at
 Manually rotate the spindle , then puffed cavity without any sound grazing , grazing if necessary to adjust the sound , detailed side
1.1.1 Adjustment screw extrusion chamber and the gap
 Check and clean water , steam road. All filters need cleaning up
 Check the bypass guide plate rotation is flexible and comfortable
To reduce vibration and ensure the puffing chamber face and the end face of the belt drive pulley shaft stationary , the motor pulley to be maintained in the same plane. This position can be adjusted on the shaft by a pulley mounted on the pulley in the middle of two sets of expansion cone structure to meet the above requirements . Drive belt is too loose, slippery , pull tight the shaft is too large , reduce belt life. By adjusting the tensioning screw on the motor guide , so that the belt tension is properly loaded state , i.e. with 29kg force of the belt at the midpoint of the straight edge . And an offset of 14mm flex it when appropriate , keeping in mind the motor shaft is parallel with the spindle. Individual protective cover in place to check whether the fuel tank and the bearing or without the occurrence of oil spills , such as the decline in the oil bearing oil circulating cooling need to be supplemented in accordance with the instructions of each motor reversing signs checked and adjusted accordingly Empty all motor running, check whether the abnormal phenomenon
1.1.1 Adjustment screw extrusion chamber and the gap
[Description]
At every turn of the screw must be guaranteed during operation and puffed cavity wall without any grazing sound. Puffing chamber such deviation , the screw in the chamber during operation of the friction and impact extrusion , will greatly affect the life of the screw , the screw directly to the break even . While in the production process , but also make the eccentric puffing chamber unstable production , and yield . Only when the host does not have any idle puffing chamber was described sound adjustment suitable for grazing .
