Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing equipment, and specifically relates to a processing system for pickled dried fruit. Background Technology
[0002] Cranberries are a nutrient-rich berry, containing abundant proanthocyanidins, ellagic acid, phenolic acids, resveratrol, and other substances with antibacterial properties. Many studies have shown that cranberries can inhibit Helicobacter pylori infection and are effective in preventing gastric ulcers, gastric cancer, and duodenal ulcers. Furthermore, the flavonoids in cranberries have antioxidant functions in both in vivo and in vitro experiments, especially flavonols and proanthocyanidins, which have a preventive effect against atherosclerosis. Cranberries also have functions such as lowering blood pressure, preventing urinary tract infections, and preventing cardiovascular diseases. They also have various health benefits, including promoting bowel movements, lowering cholesterol, and antiviral properties, thus gaining increasing popularity among consumers. However, due to the geographical limitations of cranberry production and its short shelf life and difficulty in preservation, it is primarily consumed as dried cranberries and cranberry juice.
[0003] Chinese patent CN103211002A discloses an air-source heat circulation fruit drying device and its automatic temperature control method. It includes an air-source heat pump, a dehumidifier, drying chambers, and heat pipes. The air-source heat pump, drying chambers, and dehumidifier are sequentially connected via heat pipes. The air-source heat pump is connected to a main heat pipe, which is connected to multiple drying chambers via multiple series-connected branch heat pipes. Branch return heat pipes are installed on the top of the drying chambers, and these branch return heat pipes on the multiple drying chambers are connected in series to the main return heat pipe. The main heat pipe is connected to the dehumidifier. This method, combined with a series-connected heat pipe heating process for multiple drying chambers, enables simultaneous drying of multiple varieties of fruit from a single heat source. However, it can only perform the drying step.
[0004] Chinese patent CN101849599B discloses a pomelo preserve production line, which consists of an automatic pomelo washing machine, an automatic pomelo disinfection sprayer, a blower, a chain conveyor, a pomelo slicing machine, a pomelo pulp separator, a pomelo peel dicing machine, a first conveyor elevator, a pomelo dicing device, a second conveyor elevator, a pomelo dicing debittering device, a third conveyor elevator, a preserve sugaring device, an automatic separation conveyor, a fourth conveyor elevator, a preserve blanching machine, a pomelo preserve liquid separation device, a fifth conveyor elevator, an automatic preserve dryer, a pomelo preserve cooling device, a disinfection and polishing machine, and a pillow packaging machine connected in sequence. This production line replaces manual operation in pomelo preserve production, improves production efficiency, shortens the processing cycle, meets the requirements of mass production, reduces the labor intensity of workers, minimizes human involvement in the production process, and improves the hygiene quality of the product. However, it is only suitable for the production of pomelo preserves, and it cannot separate the sugar sources remaining on the candied fruit, such as sugar syrup and granulated sugar, which can easily lead to excessive sugar sources adhering to the surface of the preserves, resulting in a sticky appearance.
[0005] Therefore, it is necessary to design a processing system suitable for small-diameter dried fruit to meet the requirements of controlling the sugar content on the surface of the dried fruit after pickling, as well as drying and dehumidification. Summary of the Invention
[0006] To address the aforementioned technical problems, this utility model provides a processing system for pickled fruit preserves, which improves production efficiency, shortens the processing cycle, meets the requirements of mass production, and can control the content of residual sugar solution on the surface of the fruit preserves, thereby improving uniformity.
[0007] To achieve the above objectives, this utility model provides a processing system for pickled fruit preserves. A first vibrating drain screen is connected to a drum sugar washing machine, the drum sugar washing machine is connected to a second vibrating drain screen, the second vibrating drain screen is connected to a first oil spraying drum, the first oil spraying drum is connected to a dryer via a first conveyor belt, the dryer is connected to a dehumidifier via a second conveyor belt, and the dehumidifier is connected to the second oil spraying drum via a third conveyor belt.
[0008] Preferably, the vibrating sieve includes a sieve body, which is connected to a collection frame via a force guide. A collection tank is provided at the bottom of the collection frame, and the collection frame and the collection tank are fixedly connected to a support.
[0009] More preferably, the sieve body is provided with a sieve screen, and the outside of the sieve body is provided with a drive motor; the bottom of the liquid collection tank is provided with a liquid outlet pipe; and the two ends of the collection frame are provided with baffles.
[0010] More preferably, the collection frame has a sieve hole at the middle 1 / 3, and the sieve hole is located above the liquid collection tank.
[0011] Preferably, the oil spraying roller includes a roller, an oil spraying pipe is provided inside the roller, and an atomizer is provided on the oil spraying pipe; the oil spraying pipe is fixed to the top of the roller by a bracket, and a second control valve is provided at one end of the oil spraying pipe.
[0012] More preferably, one end of the roller is provided with an outlet, and the outer side is provided with a housing; both ends of the outer side of the outlet are provided with outlet baffles, and the outlet baffles are movably connected to the housing.
[0013] Preferably, the roller sugar washing machine is equipped with a double water spray pipe, and a first control valve is provided at one end of the double water spray pipe.
[0014] Preferably, the roller sugar washing machine is circulated with the washing water storage tank, the washing water storage tank is connected to the sugar solution storage tank by pipeline, and the sugar solution storage tank is connected to the first vibrating draining screen by pipeline.

[0016] Preferably, the bottom of the first conveyor belt is provided with a first material spreader, which is connected to the dryer; the bottom of the second conveyor belt is provided with a second material spreader, which is connected to the dehumidifier.
[0017] The beneficial effects of this invention are as follows: By combining the vibrating draining screen and the drum sugar washing machine, excess sugar on the surface of the pickled fruit can be cleaned and separated, avoiding excessive residual sugar solution on the surface. This prevents the fruit from sticking together during drying and dehumidification, thus reducing drying and dehumidification efficiency and affecting product uniformity. At the same time, the washing water containing sugar from the vibrating draining screen and the drum sugar washing machine can be recycled when the sugar content is <20 degrees, and when the sugar content is ≥20 degrees, it can be recycled to the sugar solution storage tank for use in pickling fruit or for preparing the sugar solution before pickling fruit. This improves the utilization rate of water resources, reduces the waste of sugar, and thus reduces production costs.
[0018] The edible oil is mixed with the candied fruit twice using two spray rollers. The first mixing protects the candied fruit from rapid loss of moisture and sugar during processing and forms an oil film between the fruit pieces to prevent sticking, thus improving processing efficiency. The second mixing enhances the gloss of the candied fruit and protects it during transportation and storage, reducing clumping and other issues that affect its appearance.
[0019] This invention improves production efficiency, shortens processing cycle, meets the requirements of large-scale production of dried fruit, reduces labor intensity for workers, reduces human involvement in the production process, and improves the hygiene quality of the product.
