\u4e00\uff0eProduct Application FAQs<\/strong><\/span><\/p>\n<\/div>

Q1: What production\u2011process is the ACL\u2011DC278 spiral chiller machine designed for?<\/span><\/strong><\/p>\n

A1: ACL\u2011DC278 is a spiral\u2011type shoe freeze\u2011setting machine, specially used for freeze\u2011shaping procedures of men\u2019s, women\u2019s and children\u2019s footwear. It applies rapid low\u2011temperature treatment to freshly pressed shoes to lock shoe contours, restrain post\u2011process deformation, and stabilize finished\u2011shoe three\u2011dimensional shape. It is deployed on footwear assembly lines for continuous mass production after sole\u2011pressing or hot\u2011setting stations.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

\u4e8c. Core Features & Advantages FAQs<\/strong><\/span><\/p>\n<\/div>

Q2: What benefits does its twin\u2011spiral conveying\u2011track structure bring?<\/span><\/strong><\/p>\n

A2: It adopts internal twin\u2011spiral rail layout. Within limited floor footprint, it realizes maximum conveying length up to 17.3\u202fmeters. Longer in\u2011machine dwell\u2011time enables sufficient and thorough low\u2011temperature freezing for each shoe piece. The closed spiral path guarantees consistent cold\u2011air contact for every workpiece, improving overall freeze\u2011setting quality without occupying excessive factory floor area. Anti\u2011jump and anti\u2011jam chain design keeps conveying movement smooth and reduces chain\u2011stuck downtime.<\/p>\n<\/div>

Q3: What is the performance of its dual\u2011unit refrigeration system?<\/span><\/strong><\/p>\n

A3: Equipped with dual independent refrigeration hosts, the machine delivers powerful cooling capacity for fast temperature pull\u2011down. It meets high\u2011volume continuous production demands. Built\u2011in automatic defrost device reduces frost accumulation on evaporator surfaces, preserves refrigeration efficiency and cuts extra energy consumption caused by heavy frost layers.<\/p>\n<\/div>

Q4: How does it achieve uniform internal temperature distribution?<\/span><\/strong><\/p>\n

A4:A high\u2011efficiency internal\u2011circulation fan system drives cold air circulating inside the closed cavity, which balances temperature across all zones and lowers temperature deviation inside the chamber. The inner tank is coated with high\u2011performance thermal\u2011insulation material to minimize cold\u2011loss outward, realizing energy\u2011saving stable operation.<\/p>\n<\/div>

Q5: What functions does the intelligent control system provide?<\/span><\/strong><\/p>\n

A5:It is equipped with human\u2011machine touch\u2011screen interface. The system automatically collects and stores running data. Operators can switch monitoring interfaces to view real\u2011time status of refrigeration units, fan, chain conveyor, temperature and defrost cycles. Simple interface logic facilitates equipment status review and production\u2011data management.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

\u56db.On\u2011Site Installation & Environment Matching FAQs<\/strong><\/span><\/p>\n<\/div>

Q7: What pre\u2011conditions are required before installation?<\/span><\/strong><\/p>\n

A7:\u2011 Power supply<\/strong>: Stable three\u2011phase 380V power circuit with enough load capacity; reliable protective earthing is mandatory.<\/p>\n

\u2011 Space allocation<\/strong>: Reserve \u22651.5\u2011meter clearance on all four sides, especially at inlet\u2011outlet positions for loading\/unloading. Keep adequate rear\u2011side ventilation space for refrigeration\u2011unit heat dissipation.<\/p>\n

\u2011 Environment<\/strong>: Workshop ambient temperature should not be excessively high; avoid humid and heavily\u2011dust locations to protect refrigeration compressors, fans and electrical components.<\/p>\n

\u2011 Floor<\/strong>: Flat, high\u2011strength solid concrete ground to bear heavy machine weight and suppress vibration during long\u2011time continuous operation.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

\u4e94.Standard Startup & Production Operation SOP FAQs<\/strong><\/span><\/p>\n<\/div>

Q8: What is complete standardized operating procedure from power\u2011on to mass\u2011production?<\/span><\/strong><\/p>\n

A8:<\/p>\n

    \n
  1. Pre\u2011start\u2011up inspection<\/strong>: Check power\u2011supply grounding; inspect chain for foreign\u2011body jamming; test emergency\u2011stop function; confirm fan and refrigeration\u2011unit are in normal standby status; close all insulated access doors tightly.<\/li>\n
  2. Power\u2011on & parameter setup<\/strong>: Switch on main power, enter HMI interface; set target freeze temperature and shoe dwell\u2011time according to shoe\u2011material requirements; start refrigeration system to pre\u2011cool inner cavity until stable process temperature is reached.<\/li>\n
  3. Idle test\u2011run<\/strong>: Execute full spiral\u2011conveying empty cycles; observe chain running status, check for abnormal noise, and verify automatic defrost triggering logic.<\/li>\n
  4. Sample debugging<\/strong>: Feed sample shoe workpieces into the inlet; complete whole spiral circulation. Evaluate freeze\u2011setting effect; fine\u2011tune temperature and dwell\u2011time parameters until shoe shape\u2011fixing performance meets factory\u2011internal standards.<\/li>\n
  5. Formal mass\u2011production<\/strong>: Continuously feed shoes at machine inlet. Perform random sampling inspection each shift to check anti\u2011deformation effect. Monitor real\u2011time equipment running data on touch\u2011screen.<\/li>\n
  6. Shift\u2011end shutdown<\/strong>: Stop workpiece feeding; wait for all shoes to finish spiral circulation and exit the cavity. Stop refrigeration compressors first. Keep circulation fan running for post\u2011run ventilation. Cut\u2011off main power after cavity temperature rises moderately. Clean chain and inner\u2011cavity residues.<\/li>\n<\/ol>\n

    \u26a0\ufe0f Safety warning: Do not open insulated cavity access\u2011doors while refrigeration units are working; avoid frostbite from low\u2011temperature internal environment.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
