Process and equipment for grain moisture meter gru00e7os

摘要

Process and equipment for gru00e7os grain moisture meter. The invention relates to a process and a device for measuring the moisture contained in a sample of grain which employs the principle of distillation.The equipment for determination of the moisture contained in a sample of grain comprises a container (1) with lid (2) and a temperature measuring instrument (3) internal. On the inside of the container (1) is introduced into a specified mass of grains and an appropriate volume of oil. A pipe (4) makes communication between the container (1) and a capacitor (5).A source of carlor (6) is used for heating the container (1). A graduated container (7) is employed to cluster and measure the volume of water that evaporated from the sample grain and that was condensed.The procedure for the determination of moisture contained in a sample of grain comprises the following operations: feeding of a measured mass of grains (10) within a container (11); feeding a volume of oil (12) sufficient to cover the entire mass of GR. To (10) deposited on the inside of the container (11); - closure of the container (11) with a lid (13) which is dotADA is an instrument for measuring temperature; heating the container (11) to a temperature higher than the evaporation of water; condensation of water vapor from the container (11) with the mass of grains in a capacitor (14); - collection of condensed water in the condenser (14 ) in a volumetric flask (15); measurement of the volume of condensed water and collected in the container graduated (15);Calculation of the percentage of water evaporated in the mass of the grains, inserted in the container.
