Description

Technical Field

[0001] This utility model relates to the field of stinky tofu technology, and in particular to a stinky tofu washing device. Background Technology

[0002] Stinky tofu, a traditional Chinese fermented soybean product, is renowned for its unique "stinky smell, delicious taste" flavor, especially popular in the Jiangnan region, with a history spanning hundreds of years. Its origins are closely linked to folk wisdom, with legend suggesting it evolved from an accidental fermentation during tofu making. Through continuous refinement, it has developed into its current classic flavor. The production process is quite meticulous, requiring soybeans as the raw material. The process involves soaking, grinding, boiling, and adding coagulant to create tender tofu. The tofu is then cut into small pieces and soaked in a brine made from fermented ingredients such as winter bamboo shoots, mushrooms, and yeast for several days or even months. Under the influence of the brine, the proteins in the tofu decompose, producing various amino acids and volatile substances, which is the source of its "stinky" smell, but also gives it a delicious flavor. Once fermented, stinky tofu can be pan-fried, deep-fried, or steamed, each method resulting in a distinct flavor. Fried to a golden brown, stinky tofu is crispy on the outside and tender on the inside, bursting with juice and aroma when bitten into. Deep-fried stinky tofu has a crispy outer skin and a soft interior, and when eaten with chili sauce or sweet sauce, it offers a rich and layered taste. Today, stinky tofu is not only a classic street food, but also a culinary icon in many regions due to its unique flavor and cultural connotations. It carries people's memories and love for traditional flavors and occupies a place in the modern food industry, giving rise to a variety of processed products to meet different consumer needs.

[0003] In the production and processing of stinky tofu, the initial treatment needs to remove residual soybean powder, impurities and some fermentation products from the surface. The traditional manual washing method is not only labor-intensive and inefficient, but also prone to damage tofu blocks due to uneven force, and the cleaning effect is difficult to guarantee.

[0004] Based on the above background, the equipment must meet the core requirements of efficient cleaning, reduced tofu breakage, and convenient operation. The design must ensure that the tofu is subjected to uniform force during the washing process to avoid excessive compression; the structure must facilitate loading, unloading, and cleaning, and comply with food hygiene standards; it must also have a stable power transmission and motion mechanism to achieve automated washing, reduce labor costs, and improve production efficiency. Furthermore, the stability and safety of the equipment during use must be considered to ensure long-term reliable operation. Utility Model Content

[0005] The purpose of this utility model is to provide a washing device for stinky tofu, which solves the problems mentioned in the background art. The traditional manual washing method is not only labor-intensive and inefficient, but also prone to damage tofu blocks due to uneven force, and the cleaning effect is difficult to guarantee.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stinky tofu washing device, comprising a base, four anti-slip blocks fixedly installed on the lower surface of the base, a fixed frame fixedly installed on the upper surface of the base, the fixed frame being L-shaped, a control switch installed on one side of the fixed frame, a washing component installed at the bottom of the fixed frame, a water basin fixedly installed on the upper surface of the base, a water outlet pipe installed on the side of the water basin away from the fixed frame, and a sealing cap movably installed on the end of the water outlet pipe away from the water basin.

[0007] The washing assembly includes a motor, which is fixedly mounted on the upper surface of the fixed frame. The motor is electrically connected to a control switch. A fixed cylinder is fixedly mounted on the upper surface of the fixed frame. The fixed cylinder is hollow and a telescopic cylinder is slidably connected inside the fixed cylinder.

[0008] The inner side wall of the fixed cylinder is provided with a sliding groove, which is annular and inclined. A convex shaft is slidably connected inside the sliding groove, and the convex shaft is fixedly installed on one side of the telescopic cylinder.

[0009] The telescopic cylinder has a rectangular groove on its upper surface, and a fixed rod is slidably connected inside the rectangular groove. The top end of the fixed rod is fixedly connected to the motor output end.

[0010] The telescopic cylinder has a telescopic rod fixedly installed on its lower surface, and a bracket is fixedly installed at the bottom end of the telescopic rod. The bracket is U-shaped.

[0011] The bracket has a frame fixedly installed at its bottom. The frame is made of stainless steel and has a metal grille fixedly installed on its exterior.

[0012] This utility model discloses a washing device for stinky tofu. The primary highlight of this device lies in its innovative composite motion washing structure. The device employs a nested design of a fixed cylinder and a telescopic cylinder. Through the sliding cooperation between the annular inclined groove on the inner wall of the fixed cylinder and the convex shaft of the telescopic cylinder, combined with the sliding connection between the motor-driven fixed rod and the rectangular groove of the telescopic cylinder, a composite motion of up-and-down reciprocating and rotational movement of the washing frame is achieved. This design allows the stinky tofu inside the washing frame to achieve both vertical up-and-down tumbling and horizontal rotational stirring in the water flow. Combined with the metal grid on the outside of the washing frame, it can thoroughly clean impurities from the surface of the tofu, avoiding the problems of uneven cleaning and low efficiency in traditional manual washing, significantly improving the washing effect and cleanliness. The device base is stably placed using four anti-slip blocks, effectively preventing displacement caused by vibration during operation. The fixed frame provides solid support for the washing components, the electrical connection between the motor and the control switch facilitates operation and control, the water basin is equipped with an openable and closable water outlet pipe for easy replacement of washing water, the stainless steel washing frame is corrosion-resistant and easy to clean, the metal grid prevents tofu blocks from falling and ensures smooth water flow, the overall structure takes into account stability, practicality and durability, and is suitable for long-term use in food processing scenarios.
