Mechanized carrot growing technologies involve the use of various operations, in particular, digging by pulling the root and removing it inside the combine, as well as by pre-cutting the green mass of the root and subsequent cleaning of the heads from the remains of the root before digging. Due to the fact that there are high requirements for cleaning carrot root heads from residues, the development of new, more improved cleaners is an important and urgent task. The solution to this problem was implemented by developing a new design of the purifier, which is able to perform the specified cleaning process with high quality. The cleaner consists of two shafts that cover each row of carrots on both sides and rotate in opposite directions. Cleaning shafts are located in a horizontal plane at an angle to each other. As cleaning elements, pairs of rubber blades are used, which are installed on hubs on each shaft, which are fixed on the shafts with the appropriate step. The rubber blades are mounted on hubs hinged and the ends of the blades of one shaft are located between the pairs of blades of the second shaft. By simultaneously hitting the heads of the carrot root crops with flexible blades from both sides, the process of cleaning them from residues is carried out. In order to study the process of cleaning carrot heads from the remains of ghee on the root, an experimental installation was made and a program of experimental studies of this technological process was developed.

Geothermal energy, solar energy, industrial thermal effluents, etc. mainly offer low-temperature waters. Heating installation or system, originally developed for one of the alternative energy source. The problem of low-temperature heating of greenhouses is not characteristically only for direct application of geothermal energy but is connected to the problem of all the “alternative” energies use for that purpose. Calculations determine the losses of heat transfer, losses from the application of heat and benefit from the use of hot water. Calculated is necessary and permissible temperature of the floor, the recommended speed of the fluid and plan for layout of pipes in the ground of greenhouse.
