Mostly — pneumatic system extracts syn-propanethial-S-oxide through vent. Still recommend ventilated room.
Garlic — use dedicated GLP-001 (different geometry). Shallots — yes with shallot chuck option.
Surface-dry first. Wet skin slides on air blade, reduces peel rate. Air-dry or brush-dry.
Stronger-skinned (Stuttgart Giant) need 0.7 MPa air. Soft varieties (Walla Walla) — 0.5 MPa.
5-7 days refrigerated in vacuum or MAP packaging. For longer: freeze (BLF-001) or dehydrate (HPD-001).
Oil-less compressor (food-grade), 0.6 MPa minimum, 0.3-1.0 m³/min depending on model. We supply compatible compressors.
