Oil grinding machine for processing citrus fruits
Technical Field
The utility model relates to an oil grinding device, in particular to an oil grinding machine for citrus fruit processing.
Background
The existing oil grinding machine for citrus fruits has three types basically. A roller type oil grinding machine mainly comprises a plurality of rollers and burrs on the rollers, wherein the rollers are horizontally arranged in parallel, when the machine works, citrus fruits are driven by a motor to move forwards and roll through the rollers, the burrs pierce oil cells, oil is washed away by high-pressure water at the same time, and the process enters a post-separation process. The method is widely applied to the oil grinding working condition of large-scale citrus processing factories and is suitable for large-scale production factories. The second type is a millstone type oil mill, which is also called an Aiwena type oil mill. The raw materials are poured into a charging hopper and slowly put on a grinding disc through an automatic charging door, the fruits continuously rotate on the grinding disc due to the rotation of the grinding disc, oil cells of the peels are rubbed by a plurality of sharp pricks on the disc, and the peel essential oil flows out. The grinding disc is typically cast with corundum and cement. The third one is a rotary barrel type oil mill, the middle part is a rotary disk, the four walls of the oil mill are grinding wheels, a motor drives the rotary disk to roll fruits, the fruits are thrown to the peripheral wall under the action of centrifugal force and are inserted and broken by the peripheral wall and tiny teeth on the rotary disk, water sprayed by a high-pressure water nozzle on the upper part washes out essential oil which flows out by friction, and magnesia cement which is formed by mixing carborundum and magnesia is coated on the inner wall of a cylinder.
The second and third oil grinding machines are suitable for small-sized juice factories or preserved fruit processing factories, and the first oil grinding machine is suitable for large-sized factories. Patent publication is CN206188764U, and the name is "oranges and tangerines or navel orange mill oil machine device" patent discloses an oil grinding device, including motor and cylinder, the even horizontal arrangement of cylinder is in the frame and fastening, and the surface of every cylinder evenly is provided with acicular stinging, and the both sides fastening of frame has the wallboard, scraper means fastens on two wallboards and is located the top of cylinder, installs spray shower nozzle on the scraper means, main gear fixes in feed arrangement's side, and scraper means's preceding top is provided with feed arrangement and docks with the cylinder, material receiving device installs the below at the cylinder, and the upper portion at the machine is installed to the guard shield. The method is uniformly and horizontally arranged according to the rollers, and when citrus fruits roll through the rollers, burrs on the rollers have a fixing effect on the fruits, so that the surface of the citrus fruits is easily punctured unevenly when the citrus fruits roll forwards, and the recovery rate of essential oil is low. When a large amount of oranges are positioned on the roller of the device, the oranges in contact with the roller can be well punctured, the oranges above the oranges roll forwards under the drive of the oranges below the roller, and the oranges are easy to be not punctured or rarely in contact with burrs of the roller, so that the oil grinding device cannot play a role, the subsequent processing process is greatly influenced, and particularly the problem that the peel cannot fall cleanly or cannot fall off in the subsequent enzymolysis or peeling process is easily caused.
