DIY Food Dehydrator – Ghar Par Banana Ka Tareeqa

Step 1: Required Materials (Cheezen)

1. 140L PET crate – ₹14,000 (strong aur stackable)

2. Food-grade stainless steel mesh – Trays ke liye

3. 2 DC fans – ₹100–150 each

4. Ceramic heater – Primary heat source

5. 250–300W bulb – Secondary heat source (fine tuning)

6. Digital temperature controller with probe – ₹700

7. Aluminum foil tape – Gaps seal karne ke liye

8. Drill + 6mm drill bit – Ventilation holes ke liye

9. Insulation material – Old blanket ya foam for heat jacket

10. Wires, DC-DC converters, switches – Electrical setup ke liye

11. Markers – Tray labeling ke liye

Step 2: Prepare the Crate

1. PET crate ko clean karen.

2. 68 ventilation holes (6mm) drill karen – evenly har side par.

3. Gaps ko aluminum foil tape se seal karen, airflow block na ho.

Step 3: Build Trays

1. Stainless steel mesh ko tray size ke hisaab se cut karein:

   • Short trays: 28 × 38 × 2.5 cm (quick-dry items)

   • Large trays: Bulkier items

2. Trays ko reinforce brackets ke saath support karein.

3. Mark karen: “SHORT”, “TOP”, “GARLIC” etc.

Step 4: Install Fans

1. Bottom fan → warm air push kare

2. Top fan → air pull kare

3. Fans ko DC-DC converters se connect karein (12V supply)

4. Ensure vertical convection loop – uniform airflow

---

Step 5: Install Heaters

1. Ceramic heater → primary heat source

2. Bulb → secondary, fine-tuning

3. Temperature controller probe ko crate ke andar place karein

4. Set temperature 50–60°C

5. Timer set karein → 12 hours run, auto-off

---

Step 6: Insulation & Safety

1. Old blanket ya foam se heat jacket bana ke crate ke sides wrap karein

2. Ensure crate stable ho, wires properly insulated ho

---

Step 7: Load Trays

1. Bottom tray → high moisture items (bananas, strawberries)

2. Middle tray → medium moisture (kinu, oranges)

3. Top tray → slow-dry / aromatic (garlic, lemons)

4. Leave space between trays for airflow (~5–8 cm)

---

Step 8: Start Dehydrator

1. Power on

2. Check airflow aur temperature

3. Adjust fan speed ya heat if needed

4. Drying time:

   • Bananas → 6–8 hours

   • Garlic → 12–14 hours

   • Citrus → 8–10 hours

---

Step 9: Post-Drying

1. Trays nikal ke cool down karen

2. Dried fruits/garlic ko airtight jars me store karein

3. Clean trays → rinse & dry

Tips

• Moisture-rich items hamesha lower trays pe rakhein

• Airflow ko block na karein → uniform drying

• Winter mein insulation aur heater adjust karein

• Bulb fine-tuning ke liye use karein, case-hardening avoid karne ke liye

• Experiment karein → local fruits aur sizes ke saath
