Ploughshare mixer to be innovated and developed in foodstuff industry




Food is the most important part in our every people’s life. Bakery, spice seasoning, milk powder, flour and nutrition is what we need in daily life. Food safety is highly concered by goverment and every consumers. How to control the safety and what could influence it? Production is the first and preliminary part that every manufacturer shall take it into consideration. As for powder food, mixing is a key and final step before packing. So, the powder mixer has to be designed and manufactured to meet FDA and GMP requirement. Besides the normal rules in GMP requirement, Mixing Technology is developing and innovating better solutions for it. Firstly, we start from ploughshare mixer to be designed as shaft take out type.


In 2013, a food nutrition company Ghana found us to help them design a mixer solution for their new plant in China. Ghana is a leading global performance nutrition and ingredients group employing more than 5,800 people across 34 countries worldwide. In Europe, they use Italy brand ploughshare mixer
but they want to use chinese brand mixer in their china plant for localization. Cleaning and no contamination is the most important issue for Ghana and the project manager also want us to find a best solution for them to make mixer easy clean. Although it has cleanout door on the vessel of ploughshare mixer, it can not clean every corner and part inside mixer and it is also takes long time
to dry the mixer which affect working efficiency in daily production.


Through discussion in engineer team, we finally try to design the shaft of mixer which can be pulled out for cleaning and fast drying by air. Vortex Mixing Technology has done many experiment and innovated. First, we design screw rod and driven by gear motor to make shaft pulled out. In order to avoid plough shovels collide choppers, we install sensor on shaft and it could be stop at the same
position every time. However, the motor must be with brake in order to make shaft stop smoothly and without error. Furthermore, the sensor switch will also be installed on screw rod when the shaft pulled out at fixed position. Second, the shaft connection shall be coupling type which must be strong and stable. Third, in order to save space, the screw rod will be placed on top not bottom.

After many times test, this easy clean design type ploughshare mixer can save 2/3 effort on cleaning and drying. The worker just need to pull the shaft out and to use water jet to clean shovels. Then, using air to make water dry. Not only saving much time and labors, but also the mixer can be cleaned thoroughly. This new type mixer will be developed in more area like pharmaceutical and cosmetics. We believe that it will have a good market in near future and will be welcomed by many Europe customers.

Features of Double shaft paddle mixer

Application: This kind of conveyor is widely used in various industries, such as building materials, chemical, electric power, metallurgy, coal, grain and other industries, for horizontal or inclined conveyor dust,, granular materials and small block ect. How to choose the spiral conveyor for you: 1. How much about the capacity? Such as 5t/h,10t/h,20t/h etc. 2. How long you need conveying? Such as 5m,20m,50m,100m etc. 3. What’s material? Such as coal, cement, stone, grain etc. 4. How much about the max inclined angle? Such as 5°,10°,15°,25° etc. Tell me those data, we can help you choose the suit spiral conveyor for you. Features: 1.High-quality steel pipe with good integral rigidity; 2.Once-forming spiral double pitch paddles, which will never block the material; 3.Universal ball joint, which facilitates installation, adjustment and steering; 4.Double-pitch paddles, which decrease the compressed degree of material when being transported; 5.Standard parts and compone...

Why automatic packing machine Works for Our Customers?

Characters of Vertical Packing Machine: 1. With high environmental performance and a perfect exhaust system, thereby reducing the dust generated during the packaging process. 2. With high packaging precision, two kinds of feeding speed through the import of Mitsubishi frequency control, the whole electronic control using PLC control, the use of high-precision weighing sensor and the configuration of imported quantitative control instruments imported from Japan, the instrument can be equipped with standard interface, Communicate with the central system, the implementation of the overall control system for packaging monitoring. 3. The silo is equipped with broken arch device, in order to loose the material and avoid arch bridge. 4. Adopt bagging environment-friendly rubber-bag folder bag device, can seal the bag seal, so there will be no dust when packaging. Application The stand pouch packing machine  is mainly used to auto-quantitatively package powder and grain in the spher...

Working Principle of Screw conveyor

Features: 1.High-quality steel pipe with good integral rigidity; 2.Once-forming spiral double pitch paddles, which will never block the material; 3.Universal ball joint, which facilitates installation, adjustment and steering; 4.Double-pitch paddles, which decrease the compressed degree of material when being transported; 5.Standard parts and components, which make it is convenient for transportation; 6.High-quality reducer with heavy-duty design, large torque and low noise; 7.High-quality middle-hoisting bearing and tail bearing. Working Principle: Screw conveyor is relying on a spiral blade shaft in the trough of closed continuous rotation in order to impel the lose of material moving. At this time, the material are like the bolt, in spinning along the axial moving forward gradually, finally discharging mouth off.
