膨化機調試注意事項

膨化食品的品牌、種類、口味都很多.很多人都愛吃它,尤其是小朋友.膨化食品機械,可加工日常生活中的大米、玉米、大豆、小麥等.其主要的工作原理就是機械能轉變成熱能,用機器轉動的時候產生的熱量將食品擠壓熟,經過膨化的食品zui明顯的特點就是體積變大.膨化食品機械功能多樣使其廣泛應用于食品,飼料以及工業等領域,以膨化機為基礎,我們在此介紹在食品或者飼料處理過程中其中功能,讓我們一起看一下吧!
　　1 調試前的檢查與準備工作
1.1 調試前的檢查
調試前的檢查主要有以下幾點：
檢查各部位，特別是各段膨化腔的連接螺釘、地腳螺栓、電機座與機架的連接螺栓、膨
化腔與機架的螺栓聯接，不得有松動現象
電機接線合處的各段線路檢查
 手動使主軸轉動，此時膨化腔內不得有任何碰擦聲音，如有碰擦聲音需要調整，詳細方
1.1.1 膨化腔與螺桿間隙的調整
 檢查并清理水路、汽路。所有過濾器需清理
 檢查旁通導料板轉動是否靈活自如
為減少振動以及保證皮帶傳動的平穩性，電機皮帶輪的端面和膨化腔主軸皮帶輪端面必須保持在同一平面內。這可通過裝在兩皮帶輪中間的錐形脹套結構來調整皮帶輪在軸上的位置，以達到上述要求。傳動三角帶過松，則易打滑，過緊則對軸的拉力過大，降低三角帶的使用壽命。通過調節電機導軌上的張緊螺栓，使三角帶的張緊度處于適當裝態，即用29kg 的力作用在皮帶直邊的中點。并使其撓曲偏移量為14mm 時為適當，同時要注意電機軸與主軸平行。各個防護罩是否安裝到位檢查油箱與軸承座有無漏油的發生，如油位下降需要補充循環冷卻軸承油根據指示標牌檢查各個電機的正反轉，并作相應調整所有電機空機運轉，檢查有無異常現象
1.1.1 膨化腔與螺桿間隙的調整
【說明】
在每次開機時都必須保證螺桿在運轉過程中與膨化腔內壁沒有任何碰擦聲音。如膨化腔偏位，螺桿在運轉過程中與膨化腔摩擦撞擊，會大大影響螺桿的使用壽命，甚至直接把螺桿打碎。同時在生產過程中，膨化腔偏心也會使生產不穩定，影響產量。僅在主機空轉時膨化腔沒有任何碰擦聲音才說明調整適合。

1.2 調試前的準備工作
1.2.1 原料的準備

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 .
