What 冷凍加工食品製造 do
An English description is being prepared. Japanese description:
冷凍加工食品の種類は、魚、肉、野菜などの素材から、これらを調理した食品、米飯、めん類まで様々である。原料の選別、原料の処理、製品の凍結、包装の工程を経て製品となり、冷凍保管され出荷される。製造工はこれら工程で作業して冷凍食品を製造する。
原料の選別では、原料の質が冷凍後の品質にそのまま現れるため、新鮮さや風味、外観などの総合的な品質が優れたものを選別する。
原料の処理では、不要部分の除去、整形、重量調整など、原料の種類に応じた様々な処理を行う。農産物の場合は、剥皮（はくひ）、種子除去、切断、野菜類のブランチングや果実の糖液への浸漬（しんし）など、水産物の場合は、頭、内蔵、骨、鱗、皮などの不要部分の除去、三枚おろしや切り身、剥き身の調製などがあり、主に手作業によって冷凍前の下処理を行う。
製品の凍結では、急速凍結を行う。食品を急速凍結すると、氷結晶が小さく食品の組織破壊が少なくなる。反対に緩慢凍結をすると氷結晶が大きくなって食品の組織を破壊し、品質が劣化するので、急速凍結は最も重要な工程といえる。個々の食品を一定の形にまとめて凍結するブロック凍結と、食品をバラ凍結するIQF（Individual Quick Frozen）の2つの方法がある。
包装工程では、冷凍食品の種類や形態に応じて、生産の効率化、品質の保持、流通・消費時の取り扱いの簡便化、適正な表示などの目的で個別包装と外箱詰めを行う。包装・箱詰めされた製品は、冷凍保管され出荷される。

Today ¥3.97M → in 3 years ¥4.27M → in 5 years ¥4.48M → in 10 years ¥5.07M (10-year range ¥4.36M–¥5.88M). The model assumes pay growth of +2.5% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Each component is a percentile rank among all occupations in the same country (0–100). Weights: labor demand 25, wage momentum / openings 15, pay level 15, AI resistance 25, aging workforce 10 (Japan only), entry barrier 10.
Will AI replace 冷凍加工食品製造? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 冷凍加工食品製造
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
