La piccola macchina di essiccazione solare mobile di Shuliy è un nuovo tipo di attrezzatura di essiccazione progettata per famiglie, privati e piccoli produttori. Può essere utilizzata per essiccare verdure, frutta, cereali, carne e altro.
The temperature of this mini solar dryer is automatically controlled by an intelligent thermostat. The working temperature can be adjusted between 30°C and 60°C. It is equipped with a 50W solar panel that powers a 12V DC fan, with a daily drying capacity of 20–100 KG.
Questo prodotto è compatto e flessibile, ideale per aree con elettricità limitata. Evita i problemi della tradizionale essiccazione all'aperto come polvere e pioggia, migliorando la velocità di essiccazione, la qualità del prodotto e il colore. Utilizzando l'energia solare per generare calore si risparmia una grande quantità di elettricità, rendendolo una soluzione economica, verde ed energicamente efficiente.
Principio della essiccazione solare
L'essiccatore solare si affida principalmente a pannelli fotovoltaici e conversione termica solare per completare il processo di essiccazione. Usa l'energia solare per far funzionare la ventola per la circolazione dell'aria e il calore solare per riscaldare l'aria, ottenendo una essiccazione uniforme dei materiali. L'intero sistema è un sistema di essiccazione chiuso, pulito, a risparmio energetico e a basso costo.
Processo di lavoro
1. Alimentazione solare
Il pannello solare da 50W (DC 18V) in alto assorbe la luce solare e la converte in elettricità.
Questa energia alimenta la ventola DC da 12V per far circolare l'aria.
2. Riscaldamento dell'aria e Circolazione
La camera di essiccazione è realizzata con pannelli isolanti zincati a doppia faccia, spessi 50 mm, che aiutano a mantenere una temperatura stabile.
L'aria interna è riscaldata dalla radiazione solare, e la ventola spinge l'aria calda a circolare uniformemente attraverso ogni vassoio di essiccazione.
Questo garantisce un riscaldamento uniforme dei materiali e accelera l'evaporazione dell'umidità.
3. Deumidificazione e controllo della temperatura
Dopo l'evaporazione, l'aria umida viene espulsa tramite una presa di ventilazione regolabile in alto o sul lato (Φ150mm uscita girevole).
Il sistema di controllo intelligente integrato monitora automaticamente e mantiene la temperatura tra 30°C e 60°C, regolabile per materiali differenti.
4. Struttura protettiva chiusa
Il coperchio superiore è realizzato in vetro temprato opaco a basso contenuto di ferro con telaio in lega di alluminio. Offre buona trasmissione della luce, resistenza alla pressione e protezione dalla corrosione.
Il processo di essiccazione è completamente chiuso, prevenendo efficacemente l'ingresso di polvere, insetti e pioggia, assicurando pulizia e alta qualità del prodotto.
Costruzione della macchina di essiccazione solare
Structural overview
The solar drying machine is composed of a drying box main body, solar panels, a circulating fan, a dehumidifying fan, an intelligent temperature and humidity control system, trays, casters, and PTC electric heaters.
- The drying box
The outside box is a large oven, it was made of a 5cm double-sided galvanized sheet, and the frame is supported by a 6cm stainless steel bracket. The upper cover plate is a 32 mm-thick low-iron toughened glass, surrounded by an aluminum alloy electrophoretic frame; the workmanship is well-fitted to ensure overall thermal efficiency.
2. Internal structure
All four internal walls are equipped with heat-absorbing panels, and the surface is filled with dense small holes to help absorb solar radiation to the maximum and improve thermal efficiency.
3. Solar panel
The size of the solar panel is 530*410mm. It is installed on the left side of the solar drying box. It can be folded when not in use, which is convenient and practical.
4. Circulating fan and dehumidifying fan
Both are driven by High-power fans, hot air circulation devices, and moisture discharge devices.
Automatic control device
The control system adopts embedded installation, which is safer and more beautiful. It can achieve temperature and humidity automatic control. The equipment will automatically stop when reaching the required temperature and humidity.
Stainless steel tray
The inner tray and the bracket of the box body can be flexibly combined with a 40X40 perforated structure, and the height and the distance between the trays can be adjusted freely. Galvanized screws can be easily adjusted with a screwdriver. There are rollers on the bottom, which are convenient to push in and pull out, which is also conducive to transportation between the warehouse and the solar drying box. The tray size is 59X40X2cm, and the material is stainless steel 304 sanitary grade to ensure product quality.
Casters
There are four casters at the bottom of the box, two for guiding and two for positioning, which makes it convenient and flexible to move.
