Horizontal baking oven for peanut oil press

Abstract

The invention discloses a horizontal baking oven for a peanut oil press. The horizontal baking oven comprises a thermal-insulation shell and a baking rotating cylinder, wherein a ceramic layer is arranged on the inner wall of the baking rotating cylinder; two ends of the baking rotating cylinder are rotatably connected with two ends of the thermal-insulation shell; the baking rotating cylinder isdriven to rotate by a transmission motor; a combustion chamber is reserved between the thermal-insulation shell and the baking rotating cylinder; refractory bricks provided with combustors I are arranged at the bottom of the combustion chamber; a feeding pipe is arranged at the front end of the baking rotating cylinder, and a discharging pipe is arranged at the rear end of the baking rotating cylinder; an air outlet pipe communicated with the baking rotating cylinder is arranged on the baking rotating cylinder; and ceramic scraping plates are uniformly arranged on the ceramic layer on the inner wall of the baking rotating cylinder. The baking rotating cylinder is used for rotatably baking, and the whole peanut kernel is uniformly turned over by virtue of the ceramic scraping plates, so that the moisture is effectively removed, and the baking standard is uniform. By utilizing the ceramic layer and the ceramic scraping plates on the inner wall of the baking rotating cylinder, high-temperature clinkering can be effectively prevented, and the baking effect is qualitatively improved. The ceramic has good high-temperature stability, so that the baked peanut kernel does not have peculiarsmell and is environment-friendly, sanitary and easy to clean.

Description

technical field [0001] The invention belongs to the technical field of peanut oil press equipment, and in particular relates to a horizontal baking furnace for peanut oil press. Background technique [0002] Peanut oil is a kind of edible oil that is relatively easy to digest and easy to be absorbed by the human body. It is widely eaten in the northern region. The fragrance of peanut oil is unique and pure, that is, the content of pyrazines is high. At present, the oil extraction process of peanuts is mostly to steam and fry the peanut kernels at high temperature through a steaming furnace to remove excess water in the peanut kernels; the steaming and frying furnace is vertical, and the peanut kernels are steamed and fried at high temperature layer by layer from top to bottom. This processing method is widely used. [0003] When this method is used for high-temperature steaming and frying of peanut kernels before oil extraction, the peanut kernels need to be crushed, that i...

Problems solved by technology

[0005] Secondly, after the high-temperature flame exchanges heat with the metal furnace body, when the peanuts are in contact with the furnace body, the high-temperature environment will cause a layer of slag to remain on the inner wall of the furnace. , it is necessary to clean the inner wall irregularly, which affects the production efficiency and progress, and the formation of the slag layer is a slow process. The initial baking effect of the cleaned furnace body is good. The roasting effect begins to decline, therefore, the quality of the roasted peanut kernels gradually decreases, and the squeezed oil also gradually decreases

[0006] Moreover, when the metal furnace body is baked at high temperature, the smell of metal and the smell of burnt will cause a certain smell.

Therefore, it is almost impossible to use a stable and efficient roasting method to process whole peanut kernels, so the whole peanut roasting method is rarely used.
