Description
Technical Field
The invention relates to the field of oranges, in particular to a citrus peeling machine.
Background
Referring to fig. 1 and 2, the plant belongs to the genus rutaceae. The product has good warm and humid climate, and has cold resistance slightly stronger than that of fructus Citri Grandis, lime and sweet orange. The Rutaceae citrus subfamily is distributed between 16 DEG and 37 DEG in North latitude. Is a tropical and subtropical evergreen tree (except for Zhi, 3 genera are used for economic cultivation: trifoliate, citrus and kumquat.
Citrus includes peel 101 and pulp 104, where in this application, peel 101 refers to epicarp 101a, and mesocarp 101b. (in this specification, except for what is specifically described as the epicarp, the mesocarp, "pericarp" refers to both the epicarp and the mesocarp.) the epicarp 101a is composed of a cell layer comprising the epidermis 102 and the lipid glands 103, and the mesocarp 101b is a white spongy tissue located inside the epicarp 101 a. Pulp 104 refers to a bladder 104b that retains juice and a bladder 104a that houses bladder 104 b.
The Chinese is a large country for planting oranges, and is also a large country for producing and exporting orange processing products such as canned oranges. In the production and processing process of canned oranges, orange peeling (corresponding to peeling in the application) is an important link, the orange peeling mainly comprises mechanical peeling and manual peeling,
the mechanical peeling has low peeling rate and high breakage rate, the manual peeling has low peeling efficiency, a large amount of labor force is needed, time and labor are wasted, the production cost of enterprises is increased, and the problem of food safety exists to a certain extent.
At present, manufacturers of domestic orange cans mostly adopt a manual peeling mode, and at present, manual wages rise year by year, so that peeling equipment with high efficiency, high peeling rate and low breakage rate is urgently needed.
In the prior art, the mechanical automatic peeling mode can be roughly divided into two steps: firstly, the tearing part (similar to the tearing skin of the application) is used for puncturing and tearing the orange peel to form a tear with a certain length, and secondly, the peeling part (similar to the peeling of the application) is used for removing the orange peel tearing roll.
The peel tearing effect directly influences the peel effect, and the existing peel tearing mechanism adopts the way that the citrus is punctured by a roller with a puncturing knife edge to generate a certain length of the puncturing, so that the following problems mainly exist: 1) The depth of the broken hole of the partial citrus which is punctured and torn is too shallow, and the length is too short, so that the peeling effect is affected; 2) Part of citrus is not punctured and torn to form a crack, so that peeling effect is affected; 3) Part of citrus can be punctured by a tearing blade to puncture the citrus bag, so that the yield of the citrus is affected; 4) The number of the broken holes formed by puncturing and tearing the citrus is quite random, and quite uncertainty exists, so that the peeling effect is affected.
In summary, the peeling rate, peeling rate and efficiency of the existing citrus peeling machine are low, and the breakage rate is high (the yield of citrus is low).
