单螺旋速冻机

Spiral freezer

     随着食品工业的飞速发展，食品机械的不断革新，一种结构紧凑且占地面积小的新型、高效、节能的速冻装置——DLD、SLD系列螺旋速冻装置已成为目前大，中型速冻食品企业的选择机型。

   DLD、SLD系列螺旋速冻装置的不锈钢物料传送网带在冻结间内做螺旋式转动，从而实现物料的快速冻结。分别采用顶吹风和侧吹风的布风方式，冻结时间可选范围20~90分钟。适用于调理食品、小包装食品、分割肉、冰淇淋等快速冻结,也可用于海产品、水果和不宜流态化速冻的蔬菜产品等。

>>DLD系列双螺旋速冻装置的特征

      ◆ 结构紧凑，占地面积小：由于采用多层螺旋结构，故与其它形式相同产量的速冻机相比其占地面积小1/3至1/2。

      ◆ 设计合理，运行安全可靠：经过多年不断实践经验的总结和借鉴技术，速冻机结构设计合理，由机械、电气双重保护，运行可靠。

      ◆ 使用方便灵活：DLD、SLD系列速冻机进口出口方向可多种选择，特别适合与不同的食品生产线配套产，实现流水线生产。

         ◆ 操作简单，易于维修和清洗：对操作不要求特殊技术，经简单培训即可上岗。蒸发器由铝合金制作，容易清洗的大翅片，大限度地减少残留食品的地方，防止细菌传播；进料段设有强力清洗装置，随时将网带吹干，确保传送网带的卫生；内部空间大，易损件少。

     ◆ 适应冻品范围广：面食品、菜卷、春卷、蔬菜、水果、肉食、油炸品及其它小包装食品。

      ◆ 不锈钢结构：SUS304不锈钢材料制作，冻品可以直接摆在网带上冻结，格外平滑的网格使冻品几乎不留印记；网带两侧链片上设有挡边，冻品或盘子不易从网带上滑落。

      ◆ 的风道设计：螺旋塔和蒸发器的外围的档风板设计成对称的、流畅的环形风道，增强冻品的换热效果而又使得进、出料口不跑冷，而且操作人员也可随时进入库内查看运行情况。

      ◆ 双面不锈钢隔热库体：隔热库体采用双面不锈钢聚氨脂库板，库门为双层密封条并配有加热器，有效防止冻结。

      ◆ 可靠的传动控制：螺旋传动引进，网带运行采用变频控制，速度可实现无级可调。不锈钢电控箱，库内温度数字显示，整个设备运行可靠。

      ◆ 库内底面大水槽不渗漏，排水方便：库内整个底面用3mm厚SUS304不锈钢板做成的水槽，渗漏，清洗容易排水快。

>>Features of DLD series double helix quick freezing device

◆ compact structure and small floor area: due to the multi-layer spiral structure, the floor area of the freezer is 1 / 3 to 1 / 2 smaller than that of other freezers with the same output.

◆ reasonable design, safe and reliable operation: after years of continuous practical experience and learning from foreign advanced technology, the structural design of the freezer is reasonable, protected by both mechanical and electrical, and reliable operation.

◆ convenient and flexible use: DLD and SLD series quick freezers can be imported and exported in various directions, especially suitable for matching with different food production lines to realize assembly line production.

◆ simple operation, easy maintenance and cleaning: no special technology is required for operation, and you can go to work after simple training. The evaporator is made of aluminum alloy, with large fins that are easy to clean, so as to reduce the residual food and prevent the spread of bacteria; the feeding section is equipped with a strong cleaning device, which can blow the net belt dry at any time to ensure the health of the conveyor net belt; the internal space is large and the number of vulnerable parts is small.

◆ wide range of frozen products: noodles, vegetable rolls, spring rolls, vegetables, fruits, meat, fried products and other small package foods.

◆ stainless steel structure: made of SUS304 stainless steel material, frozen products can be directly placed on the mesh belt to freeze, and the extremely smooth mesh makes the frozen products almost leave no mark; the chain pieces on both sides of the mesh belt are provided with retaining edges, so the frozen products or plates are not easy to slide off the mesh belt.

◆ unique air duct design: the baffle around the spiral tower and evaporator is designed as a symmetrical and smooth circular air duct, which can enhance the heat exchange effect of frozen products and make the inlet and outlet not run cold, and the operator can also enter the warehouse at any time to check the operation.

◆ double sided stainless steel heat insulation storehouse: the heat insulation storehouse adopts double-sided stainless steel polyurethane storehouse plate, the storehouse door is double-layer sealing strip and equipped with heater to effectively prevent freezing.

◆ reliable transmission control: screw drive introduces advanced technology from the United States, frequency conversion control is adopted for mesh belt operation, and the speed can be stepless and adjustable. Stainless steel electric control box, digital display of temperature in the warehouse, reliable operation of the whole equipment.

◆ the large water tank at the bottom of the warehouse is not leaking, and the drainage is convenient: the whole bottom of the warehouse is made of 3 mm SUS304 stainless steel plate, which is impermeable, easy to clean and fast to drain.
