Vacuum feeding machines are widely used in industries such as medicine, food, and fine chemicals. They are designed and manufactured based on GMP and meet relevant national industry and enterprise standards. This equipment can be used for conveying powder and granular materials, with high height and long distance. It is widely used in packaging machines, tablet presses, vibrating screen separators, capsule filling machines, wet granulation machines, dry granulation machines, and other equipment. It is used in conjunction with larger output extruders, injection molding machines, mixers, granulators, crushers, non-woven fabric production lines, and more. This machine is fully automatic and does not require manual labor. The parts in contact with materials are made of stainless steel, which is easy to operate and easy to maintain. This equipment has a beautiful appearance and can be used for both powder and particle materials. It adopts the principle of vacuum airflow transportation and a stainless steel combination structure. It is equipped with a pulse back blowing device, which has a high material separation rate and can automatically control the transportation and feeding of various powder and particle materials.

工作原理operational principle

 真空加料機其真空系統采用旋渦氣泵，旋渦氣泵旋轉時，葉輪與葉片之間的空氣受到離心力的作用，朝著葉輪邊緣運動，隨著電機的高速旋轉空氣被均勻的加速，葉輪旋轉所產生的循環氣流使空氣以螺旋線的形式穿出,所以空氣以極高的能量離開氣泵以供使用,該旋渦氣泵是一種吹氣或吸氣兩用的氣泵,在真空加料系統中我們應用了它的吸氣原理。

一般來說,粉末密度和顆粒大小決定了應該采用何種方式進行傳輸.真空傳輸方法非常適合粉末顆粒,它將粉末顆粒物傳輸到加工或包裝設備中,使用該設備可避免復雜的勞動力投入及環境污染。真空傳輸系統的運作規則在于必須直接簡潔。

傳輸料斗（上料桶）通常是圓錐體，它的內部有第一過濾裝置及振打裝置（或反吹裝置）。這個上料桶通過一條長的傳輸管將產品帶入其中，當料桶處于漫溢狀態時真空泵將通過預先設定的程序自動釋放，物料從桶中因為重力的原因而從卸料活瓣落下。當料桶空了之后，真空泵通過預先設定的程序自動工作，卸料活瓣關閉料桶，料桶重新處于真空狀態，下一個循環又開始了。然而，在醫藥品工業或危險品工業中，粉末傳輸系統必須帶有第二個過濾裝置，該裝置位于真空泵旁。真空傳輸系統清洗簡便迅速，料桶在空著的時候可很快拆下清洗，固定部分的保養很容易，全套設備只有軟管和過濾裝置需定期檢查更換。真空式加料機在國外已經有了幾十年的發展過程，在我國的應用也只是近幾年的事情，

隨著真空加料機技術的發展，現在的真空加料機派生出兩大系列，即電動真空加料機采用電動泵為氣源，可移動，在沒有較大壓縮氣源的場合比較適用，同時使用費用相對較低。再有就是氣動真空式加料機采用射流真空泵，如果在一個工廠或車間需要多臺真空加料機時，就需要有較大的壓縮氣源，所以在選擇加料機時要根據自有的條件，選擇不同的加料機。真空式加料機操作簡單，按動上料機開關上料管道吸料，吸料過程結束；振動裝置或反吹裝置反吹，以防過濾器堵塞，以上兩個過程由時間程序設定控制，這樣上料振打或反吹可以循環進行。

The vacuum feeding machine adopts a vortex air pump in its vacuum system. When the vortex air pump rotates, the air between the impeller and the blades is subjected to centrifugal force and moves towards the edge of the impeller. With the high-speed rotation of the motor, the air is uniformly accelerated, and the circulating airflow generated by the impeller rotation makes the air flow out in a spiral shape. Therefore, the air leaves the air pump with extremely high energy for use. The vortex air pump is a dual-purpose air pump for blowing or suction, We applied its suction principle in the vacuum feeding system.

Generally speaking, powder density and particle size determine the method of transportation that should be used. Vacuum transportation is very suitable for powder particles, as it transfers powder particles to processing or packaging equipment, which can avoid complex labor input and environmental pollution. The operating rules of vacuum transmission systems must be direct and concise.

The conveying hopper (loading bucket) is usually a cone, which has a first filtering device and a vibrating device (or anti blowing device) inside. This feeding bucket carries the product into it through a long conveying pipe. When the bucket is in an overflow state, the vacuum pump will automatically release it through a pre-set program, and the material will fall from the unloading valve due to gravity in the bucket. After the material barrel is empty, the vacuum pump automatically operates through a pre-set program, the discharge valve closes the material barrel, and the material barrel returns to a vacuum state. The next cycle begins again. However, in the pharmaceutical or hazardous materials industry, the powder transfer system must have a second filtration device located next to the vacuum pump. The vacuum transmission system is easy and fast to clean, and the material barrel can be quickly removed for cleaning when it is empty. The maintenance of the fixed part is easy, and only the hoses and filtering devices of the entire equipment need to be regularly checked and replaced. Vacuum feeding machines have been developing for decades abroad, and their application in China has only been in recent years,

With the development of vacuum feeder technology, two major series of vacuum feeders have emerged. The electric vacuum feeder uses an electric pump as the air source, which is movable and suitable for situations without a large compressed air source. At the same time, the operating cost is relatively low. Another thing is that the pneumatic vacuum feeder uses a jet vacuum pump. If multiple vacuum feeders are needed in a factory or workshop, a larger compressed air source is required. Therefore, when selecting a feeder, different feeders should be selected based on their own conditions. The vacuum feeding machine is easy to operate. Press the feeding machine switch to suck the material in the feeding pipeline, and the suction process is completed; The vibration device or backflow device is used for backflow to prevent clogging of the filter. The above two processes are controlled by time program settings, so that the feeding vibration or backflow can be cycled.
