Process mixers and reactors are customized equipment with different capabilities that are designed and built for different pressure and temperature conditions according to process requirements. This equipment is available in atmospheric, pressure and vacuum, single-wall, double-wall and triple-wall types. The design and construction of these mixers is based on the latest standard editions of the American Society of Mechanical Engineers (ASME) and the use of up-to-date mixer technology and the creativity of the creativity of experienced mechanical engineers and (Pharmaceutical Equipment Department of mechanical engineers group - Petromana). According to the needs of these mixers and reactors, they can be used in various chemical, food, sanitary, cosmetic and pharmaceutical industries. Also, considering the necessary requirements in designing and manufacturing, injectable drugs are also widely used. All types of reactors and fermenters can be produced in the family of these products. All industrial mixers have a mechanism similar to a simple household device, they all have a power generator, power transmission, blades and a container for storing materials. Only in some types, the blade type changes depending on the ingredients that are to be mixed. The material input is a constant flow, just like a river with a very calm surface and a very turbulent depth. The liquid surface remains constant and does not mix well. In this situation, we have no choice but to change the type of blade. The available options are to design the same shaft in the liquid surface and increase the number according to the need and length of the shaft, for example, design the same shaft in the middle of the liquid, but what if the liquid becomes denser and thicker? In this study, hybrid mixers have been investigated.

The amount of solar energy received in Iran is estimated at an average of 18 mega joules per square meter per day or around 1016 mega joules per year in the country. This amount of energy is more than 4000 times the total energy consumed in the country. With this amount of received energy and having suitable lands for using the sun and the relatively simple technology of various applications of solar energy, all the energy needs of the country can be provided by using solar energy. Certainly, achieving a high yield requires spending more. Also, in cold regions, reaching a stable system requires the use of various pumps and valves. Therefore, an acceptable system is a system that results in a combination of high conditions, long life, low cost of maintenance and low cost of working conditions. In all existing solar systems, 1 or 2 water storage tanks can be used, provided that an electric element or another heat source is used in one of the tanks to compensate for heat loss resulting from static water. It is obvious that the heat loss caused by one tank is less than the heat loss caused by two storage tanks due to its smaller cross section. In the case of storage tanks, one should pay great attention to their insulation type so that it does not cause heat loss. The use of an auxiliary storage tank or a gas heating system or heating element in times of cloudy conditions will greatly help to compensate for the lack of available heat.
