單螺旋速凍機

Spiral freezer

     隨著食品工業的飛速發展，食品機械的不斷革新，一種結構緊湊且占地面積小的新型、高效、節能的速凍裝置——DLD、SLD系列螺旋速凍裝置已成為目前大，中型速凍食品企業的選擇機型。

   DLD、SLD系列螺旋速凍裝置的不銹鋼物料傳送網帶在凍結間內做螺旋式轉動，從而實現物料的快速凍結。分別采用頂吹風和側吹風的布風方式，凍結時間可選范圍20~90分鐘。適用于調理食品、小包裝食品、分割肉、冰淇淋等快速凍結,也可用于海產品、水果和不宜流態化速凍的蔬菜產品等。

>>DLD系列雙螺旋速凍裝置的特征

      ◆ 結構緊湊，占地面積小：由于采用多層螺旋結構，故與其它形式相同產量的速凍機相比其占地面積小1/3至1/2。

      ◆ 設計合理，運行安全可靠：經過多年不斷實踐經驗的總結和借鑒技術，速凍機結構設計合理，由機械、電氣雙重保護，運行可靠。

      ◆ 使用方便靈活：DLD、SLD系列速凍機進口出口方向可多種選擇，特別適合與不同的食品生產線配套產，實現流水線生產。

         ◆ 操作簡單，易于維修和清洗：對操作不要求特殊技術，經簡單培訓即可上崗。蒸發器由鋁合金制作，容易清洗的大翅片，大限度地減少殘留食品的地方，防止細菌傳播；進料段設有強力清洗裝置，隨時將網帶吹干，確保傳送網帶的衛生；內部空間大，易損件少。

     ◆ 適應凍品范圍廣：面食品、菜卷、春卷、蔬菜、水果、肉食、油炸品及其它小包裝食品。

      ◆ 不銹鋼結構：SUS304不銹鋼材料制作，凍品可以直接擺在網帶上凍結，格外平滑的網格使凍品幾乎不留印記；網帶兩側鏈片上設有擋邊，凍品或盤子不易從網帶上滑落。

      ◆ 的風道設計：螺旋塔和蒸發器的外圍的檔風板設計成對稱的、流暢的環形風道，增強凍品的換熱效果而又使得進、出料口不跑冷，而且操作人員也可隨時進入庫內查看運行情況。

      ◆ 雙面不銹鋼隔熱庫體：隔熱庫體采用雙面不銹鋼聚氨脂庫板，庫門為雙層密封條并配有加熱器，有效防止凍結。

      ◆ 可靠的傳動控制：螺旋傳動引進，網帶運行采用變頻控制，速度可實現無級可調。不銹鋼電控箱，庫內溫度數字顯示，整個設備運行可靠。

      ◆ 庫內底面大水槽不滲漏，排水方便：庫內整個底面用3mm厚SUS304不銹鋼板做成的水槽，滲漏，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.
