Justification of the parameters of the disc plough

One of the most important tasks of agricultural production is to obtain food products of plant origin, which include grain legumes, vegetables, fruits, etc. Long-term storage of many kinds of plants in their natural form under normal conditions is not possible and requires the use of processing, such as drying. A special niche is occupied by medicinal plants, on the basis of which medicinal preparations, biologically active additives (BAAs), as well as spices for food are produced. Nowadays, out of 100 thousand medicines used in the world medical practice, medicinal preparations made of plants make up more than 30%. In our country the share of such remedies and preparations is about 40%. In addition to natural methods of drying, artificial methods are widely used with the help of special drying units. This requires large amounts of electrical or thermal energy from fuel combustion, as more than 65,000 tonnes of medicinal raw materials are harvested in our country each year. It is not always possible to achieve the required product performance. The use of electric energy seems to be the most preferable, since it eliminates the costs of delivery, storage of solid or liquid fuel, reduces environmental damage, and obtains the necessary properties through “fine” control of the drying technology. Currently, farms and individual farms specialise in growing medicinal plants and supplying medicinal raw materials for homeopathic pharmacies and pharmacological industries. In this regard, improving drying methods and creating small capacity electric drying plants that ensure an efficient technological process and reduce the energy intensity of drying is an urgent task.

“…Every year in our country, energy consumption for cocoon processing accounts for 16% of the total energy consumed for drying. Decreasing energy resources and rising energy prices, in turn, require the development of energy-saving technologies and accelerate their introduction into production [1][2][3].…”

Research of the influence of mulberry silkworm cocoon structure on drying kinetics

et al. 2022

This article presents an experiment on drying mulberry silkworm type 3 cocoons using universal infra-red drying equipment. Three types of cocoons, Bombyx mori, Antheraea pernyi and Antheraea mylitta, were used as an object of research. A universal (convection) drying equipment with an infrared heat source was used, which allows a fairly wide variation of the operation and load parameters (chamber temperature °C and air speed up to ±0 °C). t1 = 70 °C, air velocity up to ω = 0,7 m/sec and the drying load volume Pc = 0,5 kg/m2. The parameters that ensure the maximum intensity of the drying process while maintaining the quality properties are: coolant temperature in drying equipment within t1 = 65 …75 °C and the air velocity, which gives the best performance with the lowest possible losses in the ranges of ω = 0,6 − 0,7 m/sec.

“…"Globally, 1.6 billion dollars are spent annually to grow a variety of agricultural crops. Considering the fact that more than a hectare of land is cultivated" [1], the development of machines and equipment for high-quality and productive work and energy-efficient tillage is one of the most important tasks [2][3]. At the present time, more attention is being given to the construction as well usage of ploughs with low power consumption.…”

In recent years, due to the steadily crept of implementaton of energy and resource saving technics and technologies as well machines in agricultural branch, the utilising of ploughs in the main tillage (ploughing) in the form of spherical disks, ie the working body. In this article we present the results of experiments and research to substantiate the distance from top to bottom side H1 of support disc of disc plough to the bottom side mounting area of the suspension device and the diameter of the support disc of the plough. This means that the distance from the support disc to the lower mounting points of the suspension device should be in the range of 650-700 mm to ensure that the disc plough is well immersed in the ground and the driving depth is stable and the required transport clearance is maintained. Diameter of the support disc should be in the range 500-550 mm, so that the width of coverage is stable.
