Button Mushroom Cold Rooms — 0-4°C Storage
Cold rooms engineered for fresh button mushrooms (Agaricus bisporus) — holding 0-4°C at 90-95% humidity to keep caps white, closed, and premium. Built with PPGL PUF panels, from ₹3 lakh.
What Is a Button Mushroom Cold Room?
A button mushroom cold room is a PPGL PUF-insulated walk-in room engineered specifically for Agaricus bisporus — the white button mushroom. It maintains 0-4°C and 90-95% relative humidity, the tightest band of any common mushroom, to keep caps closed, white, and firm. Combined with pre-cooling, it extends button mushroom shelf life from 1-2 days to 7-10 days, protecting the premium grade that hotels and retail chains pay for.
