初步规划结果，基于所示输入与假设。
直接答案
所需风量 = 舍宽 × 侧墙高 × 目标风速。14 米 × 2.6 米断面在 2.5 米/秒时约需 91 立方米/秒（193,000 cfm），计入进风损失约相当于 8 台 48 英寸 25,000 cfm 风机。
使用方法
- 输入舍宽与侧墙高度。
- 根据气候选择目标风速。
- 购置风机前按进风损失增加 15%。
Scope of this tool
What this tool can and can't do
根据舍体尺寸计算隧道风量与风机数量。 is a planning tool for budget-stage and RFQ-stage decisions. It gives defensible numbers to compare suppliers against — it is not an engineering, veterinary or financing approval.
What it can do
- Size the required line capacity in tonnes per hour from annual tonnage, shifts and realistic uptime.
- Estimate connected load and specific energy consumption (kWh per tonne) by process stage.
- Show the effect of automation level, process type (pelleting versus extrusion) and utilisation on cost per tonne.
- Give an indicative CAPEX band and payback range for budgeting.
What it can't do
- Substitute for a vendor's guaranteed capacity or energy figures — those come with the equipment contract.
- Include site-specific electrical infrastructure, transformer upgrades, grid tariffs or generator backup unless you add them.
- Model your actual formula's grinding and conditioning behaviour, which changes energy per tonne materially.
- Serve as a bankable feasibility study or a financing document.
Required inputs
- · Target annual production in tonnes
- · Operating hours: shifts per day, days per year, expected uptime %
- · Process type (mash, pelleting, extrusion) and automation level
- · Energy tariff and labour cost if you want operating cost output
Example run
- · 60,000 t/year, 2 shifts, 300 days, 85% uptime
- · Pelleting line, semi-automated
- · Energy tariff 0.11 USD/kWh
- → Required nominal capacity: about 16-17 t/h
- → Specific energy: roughly 42 kWh/t (grinding + pelleting + handling), about 4.6 USD/t at the tariff entered
- → Indicative CAPEX band and simple payback range for budget-stage comparison
哪些因素会改变结果？
- · 产品结构与配方切换次数
- · 粉碎与混合的循环时间
- · 各配方的制粒或膨化速率
- · 班次与有效运行小时
- · 停机、维护与工艺效率

FAQ
Common questions
为什么用风速而不是每只 cfm？
隧道舍按鸡体表面的风冷效应设计：炎热地区出栏期 2.5-3.0 米/秒，温带地区约 2.0 米/秒。
进风口会影响结果吗？
会。进风面积与静压决定实际风量，建议按铭牌值降容 10-15%。
