Valve-type plunger homogenizers are designed for one-, two- and three-stage homogenization.
This process takes place in a special valve system, which is the center of the entire homogenization process. When passing through the smallest openings in the valve under high pressure and constant monitoring, the product finds itself in conditions of high turbulence, which is the most effective mechanism for dividing into particles. The degree of fragmentation depends on the hydraulic conditions in the valve slot area.
These conditions are mainly determined by the homogenization pressure, which determines the speed of movement of the ointment in the valve slot and its height, which determines the hydraulic radius of the flow. Valve-type homogenizers use multi-plunger high-pressure pumps with three, five and even seven plungers. When the plunger moves to the left, the ointment passes into the cylinder through the suction valve, and when the plunger moves to the right, it is pushed through the discharge valve into the chamber on which the pressure gauge is installed for pressure control.
Next, the ointment is sent through the channel to the homogenizing head, in which the valve rises, pre...
Powders are packed in the following materials.
Paper capsules. For their manufacture, the following are used: glued paper is a cellulose mass with a glued layer of animal glue. Such paper is mainly used for packaging hygroscopic and non—volatile powders; waxed and paraffin paper is glued paper impregnated with wax or paraffin. Since it does not allow moisture and gases to pass through, it is used for packaging hygroscopic substances (euphyllin), as well as substances that change under the influence of oxygen in the air and carbon dioxide. Such packaging is not suitable for camphor and menthol, which dissolve in wax and paraffin. In paraffin paper capsules, substances such as analgin, glucose, dibazole, diphenhydramine, etc. are released; parchment paper is obtained from non—glued paper treated with sulfuric acid.
It is recommended for packaging powders containing menthol, camphor and other substances soluble in wax and paraffin. It is used for packaging oily and adhesive-prone powders. Cellophane is acetylcellulose films impregnated with cellulose varnish to reduce moisture permeability. It is used in the same cases as parchment paper.

A V-shaped mixer, inside of which there is a shaft with petals, which breaks up the powder flows, additionally mixing it.
And in general, there are no universal powder mixers that are effective in 100% of cases.
The vacuum sublimation dehydration method combines the advantages of two well—known dehydration methods - freezing and vacuum drying.
During freezing, undesirable changes in the properties of the product are minimal, and during subsequent drying, frozen moisture is removed, which allows the products to be stored in appropriate packaging (for a year or more) at an unregulated ambient temperature. The energy costs for organizing the sublimation process in vacuum are 15-20 times higher than the similar costs for thermal drying. In addition, vacuum freeze dryers are characterized by high cost, high operating costs and complexity of maintenance. Among other things, according to such qualitative characteristics of the product as flowability, shape and particle size, vacuum freeze drying is not always suitable.

1. This equipment is attractive only because it is available in Russia and there is no need to wait for it.
2. The cost is much lower than now you will buy new equipment.
3. If desired, you can invite (for money) specialists from the factory and set up everything in Russia, you can order spare matrices without problems in any other factory.
On machines for boilies. I recommend you this model for balls of 5 and 10 mm. The cost, taking into account the replacement equipment, is 6000 USD, the price includes delivery to the door. For balls with a diameter of 15.20 and 25 mm, you need to take separate machines. It does not work to make replaceable shafts. The cost of each car is 3000 USD The price includes delivery to the door.
Here are my tips for you.
1. You need to pick up samples of the products that you are going to produce. Examine all the parameters for each position. According to the tablets - what diameter and thickness are they, is there a protective shell, what type of packaging, how many tablets in one package, the size of the package, will the packaging be in a cardboard box? will there be a label application, expiration dates, etc. How many tablets per hour you will need to produce, how many packages per hour you want to receive. Ampoules and solutions are the same. Learn the subtleties of everything you want to produce.

The acquaintance of a person with soft medicinal forms occurs in the first days of life, when the caring hands of a mother apply baby cream to the delicate skin of a child. Then, throughout their lives, people use soft medicinal forms of medical appointment for the prevention and treatment of various diseases in dermatology with external therapy of skin lesions of various etiologies, gynecology, proctology, ophthalmology, as well as cosmetics to protect the skin from harmful effects and prolong its beauty and youth.
In this chapter, classifications will be given, technologies for the production of soft dosage forms will be considered. Depending on the consistency, degree of viscosity and elasticity, the following can be attributed to soft dosage forms: Ointments; creams; Gels; Pastes; Liniments; suppositories; soft gelatin capsules (Capsulis); plasters (Emplastra).
Ointments are a mild dosage form for topical use, intended for application to the skin, wounds or mucous membranes. They represent the most optimal dosage form in which it is possible to combine components that are different in chemical nature, aggregate states, prescriptions and biological activity. This is due to the...
The production of liquids for electronic cigarettes is now being developed by a lot of people. And I see that there will soon be high competition in this niche. The process itself can be divided into 2 stages. 1. Preparation of the liquid itself. 2. Filling, capping and labeling. About the first part - cooking. You must have some kind of chemical technologist who will understand how and under what conditions you need to mix the components of your liquid. Is there a delamination of liquids, is there alcohol, etc. Depending on the components, the mixing equipment is selected. About the second part - filling, capping and labeling. The main consumable part is bottles, spouts, lids, labels. The gravity of the liquid itself is not high.
I can offer you two ways of implementation. Make products similar to what all your competitors do or produce a unique type of packaging. Regarding the unique packaging, the machine itself makes mini bottles from rolled materials, pours liquids there and seals these bottles. The design of the bottles you can make your own and for any volume in ml. You can also provide a break-off spout. In advance, in the printing house, you can apply any image to the rol...
