spice powder grinding machine- China Manufacturers Suppliers Factory

To plan a spice powder production line,we need to consider about the spices which need to be milled, and then we need to consider about the machines we will need.

Usually, a spice factory will grind a lot of different spices.

For example: cinnamon,chilli,ginger,turmeric,black pepper,cumin,coriander seeds....etc

Some spice is big, some spice is small. How to grind so many different spices into powder by just one spice powder line?

Recently we have a client from Palestine,they have a big spice factory which has a long history, they need to expand their factory and ask us to provide a complete spice powder production line for them.

At first, they told us their requirements.

1) Capacity shall be 300~600 kg/hr

2) One spice grinding machines can process all of their spices (they need to grind a lot of spices)

3) They hope the spice powder grinding machines are automatically and sanitary

4) They hope the spice powder is even, powder size around 30 mesh, or around 60 mesh

5) They hope the machines for grinding spices can also make flakes,like chilli flakes,black pepper flakes,not only powder

6) They request a metal detector is designed in the spice grind machine,too

7) They hope there is not much heat produced in the grinding process because heat will affect the spice powder’s quality.

What below is what we designed and provide to them.

This spice grinding line includes 8 machines, they are

1) Belt conveyor 

2) BSC coarse crusher 

3)BS screw feeder 

4）Metal Detector machine

5) BS spice hammer mill 

6) Air cooler Machine 

7) Spice sifting machine 

8) Vacuum feeder

Let’s me explain more about this grinding machines for spices

1) About feeding the raw spices, there are types Popular spice conveyor machines, one is screw feeder, one is belt conveyor.

Belt conveyor is good for sending big raw materials and flakes;

Screw feeder is better for sending small granules or powder like cumin, seeds,grains.

Considering the budget, not many clients can afford two conveyors for only one crusher,and we recommend belt conveyor finally.

2) About BSC coarse crusher,It can break big raw materials into granules or flakes.

For example,we cannot feed cinnamon into the spice powder grinding machine directly.

For material like ginger and turmeric,it is not very big,but if feed the big ginger directly into the spice milling machine, the screen inside the mill will break easily.

Besides, BSC coarse crusher can also crush chilli into chilli flakes and black pepper into small granules rather than spice powder.

3) About spice metal detector machine,there are also two types: belt type and drop type.

Considering the client will process many different spices, we still recommend belt type.

(drop type is chosen for working on powder or very small granules)

Why we add a belt conveyor in this part,not all spices needs to be crushed firstly.

For example, if you need to grind cumin, you just need to feed the cumin in screw feeder which is under the crusher, then the cumin will pass the metal detector and be sent into the spice grinder machine.

Besides,metal is forbidden to be fed into our spice milling machine, metal will harm or ruin the hammers and sieves inside the spice powder mill.

To remove the metal from spices will be very necessary.

4) Spice hammer mill is included by 4 parts: mill part, cyclone,filter box and blower.

There is mesh screen in mill chamber, and it can adjust the powder size by changing different screens. For example, if you need spice powder, you can put 1.5mm screen or 1 mm screens in mill; if you don’t need very fine powder, you can try to change 2mm, 3 mm screens.

The powder will discharged from the cyclone automatically.

And there is no fly dust during production.

5) Air cooler machine sends cold air into the mill chamber of our BS spice powder grinding machine,it will cool the mill chamber. Otherwise,the spice powder discharged from the cyclone is a little hot. The cold air Temperature is around 5 ℃.

6) Spice sifting machine is put under the cyclone of the spice grinder machine.

The lowest output is for fine spice powder, a barrel can be put under it.

The highest output is for coarse spice powder,it is connected with a small stainless steel barrel and at the bottom of it, a vacuum feeder is connected with it.

Spice sifting machine is very popular in spice plants, it can make sure that the spice powder’s size is even

7) Vacuum feeder in this line is used for connect sifting machine and feeder hopper of our grinding machine for spices. (the vacuum hopper is set above the spice mill’s feed part)

For example, we put a 30 mesh sieve in the sifter machine, powder pass the 30 mesh sieve will be discharged from the bottom output of the sifter, and powder cannot pass the 30 mesh will be sent back to the spice milling machine again by the vacuum feeder automatically. (only a few powder cannot pass 30 mesh)

With this siting system,all spice powder we get are fine and even.

Here are some picture of our machine for grinding spices

This is video of our spice powder production line, in this video,we are grinding cinnamon into cinnamon powder.

This is another video of our spice grinding machine, in the video, we are grinding ginger.

A set of BSR series robbon blender is packed,it will be used for mixing spice powder and grains.

BSR ribbon mixer is widely used in solid-solid(powder material) and solid-liquid(powder material-fluidity material) mixing in the fields of chemical industry, pharmacy, foodstuff industries.

Last Sunday, our cilent from Canada came to our factory to test our machine.

He is interested in our cryogenic grinding mill machine and wants to use it to grind bamboos and leaves. He was very satisfied with the grind effect.

This machine uses liquid nitrogen as cooling medium,can grind heat-sensitive material into fine powder, if you want to grind fruit, vegetable, herb, medicine, plastic and rubber...etc, our cryogenic grinding machine is very suitable.

Our BSDF advanced hammer mill is suitable for grinding dry spices, grain, herb and other food into fine powder.

Its mill part includes 3 groups of knives, they are

1) coarse crush knife group,

2) middle fine crush knife group,

3) fine milling knife group. Each group has one unit of knives and one liner.

Crusher part of our BSDF spice grinding machine:

Work principle of BSDF spices grinder machine:

BSDF advanced hammer mill unit includes

1) mill part;

2) cyclone (discharge system);

3) dust collecting system;

4) blower;

5) electrical control box.

Material is fed into the mill chamber, pass through the high speed rotation caused by the three groups of knives one by one.

Material is crushed three times in one mill chamber, then become fine powder.

Between middle fine crush knife group and fine mill knife group, there is a device designed for preventing coarse granule going to fine milling area, so powder fineness is assured.

The rotor speed is controlled by inverter, different particle size is achieved by adjusting rotation speed.

Advantages of BSDF herb grinding machine:

1)  No need screen or sieve in mill chamber, change powder particle size by changing speed through inverter;

2)  Because it has no screen in mill chamber, it can make finer powder than common hammer grinder machines.

3)  The mill part combines coarse crusher, middle fine mill and fine mill together, which means it can makes fine powder directly from big raw material, very effective. Then, no need to crush big material firstly.

4)  It can save more power, its capacity is much bigger than other traditional hammer mills.

Its capacity is from 100-2000 kg/h, below are technical datas of BSDF spice powder grinding machine.
