The principle of the blender, how to use the blender

The working principle of the mixer: it is composed of a horizontally rotating container and rotating vertical stirring blades, etc., when the forming material is stirred, the container turns to the left, the blade turns to the right, due to the effect of countercurrent, the movement direction between the particles of the forming material is crossed, and the opportunity of mutual contact increases, the extrusion force of the countercurrent mixer on the material is small, the calorific value is low, the mixing efficiency is high, and the mixing is relatively uniform. Mixer principle:

Centrifugal principle, when the floating liquid containing fine particles is stationary, the floating particles gradually sink due to the action of the gravitational field. The heavier the particle, the faster it sinks, and conversely, the particle with a smaller density than the liquid will float.

A blender is determined by multiple parameters, and it is impossible to describe a blender with any single parameter. Shaft power (p), paddle discharge (q), head (h), paddle diameter (d) and stirring speed (n) are the five basic parameters that describe a mixer. The liquid discharge of the propeller is proportional to the flow rate of the propeller itself, the primary square of the propeller speed and the cubic of the propeller diameter.

The shaft power consumed by agitation is proportional to the specific gravity of the fluid, the power standard of the propeller itself, the cubic of the rotational speed and the fifth power of the propeller diameter. In the case of a certain power and paddle form, the paddle liquid discharge volume (q) and the pressure head (h) can be adjusted by changing the matching of the diameter (d) and speed (n) of the paddle, that is, the mixer of large diameter paddle with low speed (to ensure that the shaft power is unchanged) produces higher flow action and lower pressure head, and small diameter paddle with high speed produces higher pressure head and lower flow effect. In the stirring tank, the only way to make the micro-clusters collide with each other is to provide an adequate shear rate.

From the perspective of the mixing mechanism, it is precisely because of the existence of the fluid velocity difference that the layers of the fluid are mixed with each other, so the mixing process always involves the fluid shear rate. Shear stress is a force that is the real cause of bubble dispersion and droplet breakage in agitation applications, among other things.

It is important to note that the shear rate of the fluid at each point in the stirring tank is not uniform. The study of the shear rate distribution shows that there are at least four shear rate values in a stirring tank, which are: Experimental studies show that the maximum shear rate and average shear rate increase with the increase of rotational speed regardless of the paddle type, regardless of the paddle diameter.

However, when the rotational speed is constant, the relationship between the maximum shear rate and the average shear rate and the diameter of the blade is related to the slurry type. When the rotation speed is constant, the maximum shear rate of radial blades increases with the increase of blade diameter, while the average shear rate is independent of the size of the blade diameter. These concepts regarding the shear rate of the paddle zone require special care in the scale-down and scale-up design of the mixer.

Compared with large tanks, small tank mixers often have the characteristics of high speed (N), small paddle diameter (D) and low blade tip speed (ND), while large tank mixers often have the characteristics of low speed (N), large paddle diameter (D) and high blade tip speed (nd).

Mixer is a kind of construction machinery, mainly used to mix cement, sand, all kinds of dry mortar and other building materials. This is a machine in which a shaft with blades rotates in a cylinder or trough to mix a variety of ingredients into a mixture or a suitable consistency. There are many kinds of mixers, including compulsory mixers, single-shaft mixers, double-shaft mixers, and so on.

How to use the multi-purpose mixer:

1. Squeezing function: wash the fruits and vegetables to be squeezed, peel them, remove the core, cut them into small pieces, and cut them into the size of the feed port. Then you need to buckle the safety buckle of the machine, plug in the power supply, press the power button, start the machine, and slowly put the pre-cut vegetables or fruits into the trough, and at the same time, you need to use the push rod to slowly push the inside of the machine, so that there will be vegetable juice or fruit juice flowing out.

2. How to use the mixer as a fruit pulp machine: connect the host and the cup holder, and then tighten the jam cup and the knife holder, and then open the lid of the cup, put the vegetables or fruits that need to be stirred into the cup, and then cut the vegetables or fruits into pieces after washing them in advance, then add an appropriate amount of cold boiled water, and then cover the cup lid. Finally, you need to put the knife holder and the cup on the base, here you should pay attention to be sure to put the machine flat and tighten it, and then fasten the safety buckle, and then turn on the power supply, so that it can be stirred into jam.

If you want to make soy milk, you need to install a filter screen, and then put the soaked soybeans into the cup from the feed port of the cup lid, then add a certain amount of water, cover the lid, turn on the power, and it can operate normally, and the filter can filter out the residue of soybean milk, making the taste of soy milk excellent.

3. How to use the multi-functional mixer as a meat grinder: first of all, you need to add a sealing ring to the knife holder, and then you need to wash the meat that you grind, remove the bones, peel and tendons, and cut it into slices and put it in the cup. The amount of each time you put it in needs to be put in according to the regulations of different products, and then add a small amount of oil or water, after putting it down, turn on the power, but it can work normally, of course, when grinding meat, you can add some seasonings according to the needs of taste, and here I also remind you that the grinding time should not be too long, otherwise it will affect the taste of the meat.

1. Before using the blender, you need to wash the food and cut it into cubes for later use.

2. Put in the blade assembly first, and then put the chopped food directly into the blender.

3. Add water or milk to the machine and close the lid of the mixer tightly to avoid overflow. Plug in the power supply and press the switch for 10-20 seconds. When performing this step, press the button for a long time for no more than 30 seconds, and if you do not finish chopping after 30 seconds, please let the product rest for 2 minutes before continuing to work.

4. After stirring, unplug the power supply, and the food from the blender will be made.

5. After drinking, rinse the parts of the mixer with clean water, if it splashes into the mixer during the mixing process, disassemble the machine and clean it, wipe it dry with a dry wet rag during cleaning, and put it in the cabinet or kitchen after wiping.

According to its working principle, concrete mixers can be divided into two categories: self-falling type and compulsory type.

1. The inner wall of the mixing drum of the self-falling mixer is welded with arc-shaped blades, when the mixing drum rotates around the horizontal axis, the blades continuously lift the material to a certain height, and then fall freely and mix with each other to make the concrete in the mixing drum evenly mixed;

2. The compulsory mixer is mainly mixed according to the shearing mechanism, and there are blades rotating with the mixing shaft in the mixer, and the blades rotate at high speed to drive concrete mixing.

Concrete mixers can be divided into three types according to their working principle:Compulsory mixerSelf-falling mixerVertical shaft mixer

Compulsory mixerIt is through the rotation of two horizontal and horizontal two stirring shafts inside the mixing silo to drive the stirring arm and stirring blades on the stirring shaft to carry out compulsory mixing of various materials entering the mixing silos.

Self-falling mixerIt is through the rotation of the mixing silo that the material inside it is constantly falling freely, so as to mix and mix.

Vertical shaft planetary mixerThe structure of the mixing system is erect, and the mixing arm and mixing blades are distributed in all directions at a reasonable angle. When working, as the spindle rotates, the individual stirring blades make planetary motion. When running, when the spindle rotates, the blades are driven to force the material to be squeezed and turned over for compound actions.

There is no dead angle in the mixing process, which is suitable for stirring materials with small particle size and high requirements for uniformity.
