Frankincense, myrrh, and dried blood are all precious resin based medicinal herbs. Due to its tendency to soften and adhere when heated; The special property of being prone to clumping and sticking due to moisture makes crushing difficult. It can soften, melt, and stick to the machine due to heat, resulting in inability to crush or even damage to the equipment.

Beijing has pioneered Tonghe's ultra-low temperature ultrafine crusher, which can solve this crushing problem with a fineness of up to400-500The eyes.

1、 Introduction to commonly used crushing methods:

1）Liquid nitrogen low-temperature crushing technology:

Principle: Using liquid nitrogen（-196℃) or dry ice（-78℃) instantly cools frankincense, myrrh, and other ingredients below their brittleness temperature, transforming them from "tough" to "brittle", making them easier to crush without losing their active ingredients due to heat.

The crushing steps include pretreatment, deep freezing, crushing, sieving, and other steps.

Advantages:

The powder has uniform fineness, does not stick to the wall, does not lose volatile oil, and has good quality.

Disadvantages:

High cost, high consumption of liquid nitrogen, requiring the purchase of specialized equipment such as liquid nitrogen tanks, pre cooling chambers, etc. Additionally, there is a certain degree of danger (such as operators being frostbitten by liquid nitrogen).

2）Mixed crushing method:

Crushing principle:

Mix the frankincense of the easy to stick machine/Mix and crush myrrh with a large amount of other medicinal materials or excipients that are not easily sticky and have strong moisture absorption. These auxiliary materials can absorb the heat generated by crushing and prevent resin adhesion.

Common "grinding companion" materials: White sugar, Rice noodles, magnesium oxide, calcium carbonate or a large amount of dried rhizome medicine powder (such as licorice, poria cocos, etc.).

The crushing steps include mixing materials, crushing, etc. Due to the assistance of auxiliary materials for heat dissipation and adsorption, the material is not easily melted and can be basically crushed until120The eyes.

Advantages:

It can achieve the purpose of crushing and has low cost.

Disadvantages:

There are quite a few excipients that need to be added, and this method is not suitable for those that cannot be added due to process requirements or for those that affect the quality of the formulation due to excessive excipients.

2、 Beijing creates Tonghe ultra-low temperature ultrafine grinder:

Our crushing equipment can directly crush the above materials and achieve high fineness. The specific advantages are as follows:

1No need to add any auxiliary materials, can be directly crushed, and the finished product has high purity.

2Low usage cost, no need for liquid nitrogen, dry ice, etc.

3No need to add any auxiliary facilities or equipment, reducing costs.

4The fineness can reach400-500The eyes.
