In this research, an ejector was designed and manufactured from brass metal as part of a cooling system to cool agricultural products, work of ejector is based on the Venturi principle. The primary fluid is air and steam of product is the secondary fluid, used the primary pressure (1, 8, 1) bar for the purpose of conducting the experiment. The ejector was manufactured from a number of interconnected parts to give the final shape. The performance of the ejector was analyzed theoretically, through operating of system evaporation of water take place in vessel leads to cooling product at change operation condition and the examination, it was reached: a- The cooling efficiency of the product increases by increasing the primary pressure. b- The cooling efficiency of the product increases by decreasing the mass of the product. c- The loss weight of the product increases by increasing the primary pressure.
